You can take care of Ekiller easily, nobody puts 5 Liepard and 1 Pawmot/Rabsca on team. You can't do anything against the stall except ragequit. It's a hilarious uncompetitive mechanic and gameplay
I have successfully beaten stall with an assist team, though I consider this to be an EXTREMELY lucky battle, not only did they have zero hazard removal but I also happened to pull metronome court change to get up rocks, allowing me to make progress:

Any playstyle can be broken with a well played turn. That doesn't mean anything. Revival Blessing teams can be easily tweaked to handle Ekiller. Mega Gengar can switch into a predicted Extremespeed and Encore Arceus.
Encore can be called by assist and thus can't be used on an assist team, if you did use it then you could no longer guarantee a revive, which is the whole point of using liepard + pawmot in the first place
No a well played ekiller really just breaks it. And there’s sincerely kinda nothing in “hilarious” in those kind of strats. Just a waste of time overall...
Depends on the set and the team, I'll exemplify this with my current assist team:
https://pokepast.es/09956afdb6d57e0b
(Shedinja's tera type can be Fairy, Ground or Steel, they each have different strengths and weaknesses)
Here's the overall EKiller plan for this team:
Any EKiller that doesn't have Toxic or Sandstorm can be walled with Shedinja-Fairy unless the opposing team has Tyranitar and Shedinja-Ground will wall it even if Ttar is present, EKiller without Shadow Claw or Toxic (such as SD/Recover/EQ/ESpeed) can also be walled by Shedinja's Bug/Ghost form even with Tyranitar on the opponent's team, as every time Ttar comes in and Shedinja dies, Liepard comes in and revives it
Against EKiller with Toxic, Teraghost Ditto will always get at least one chance to attack it, what Ditto does depends on the circumstances, but first, here's what the calcs look like from both sides:
+2 252+ Atk Arceus (Ditto) Extreme Speed vs. 252 HP / 4 Def Arceus: 231-273 (52 - 61.4%) -- guaranteed 2HKO
+2 252+ Atk Arceus Extreme Speed vs. 252 HP / 4 Def Arceus (Ditto): 231-273 (77 - 91%) -- guaranteed 2HKO
Teraghost calcs:
+2 252+ Atk Arceus (Ditto) Shadow Claw vs. 252 HP / 4 Def Arceus: 404-476 (90.9 - 107.2%) -- 43.8% chance to OHKO
+2 252+ Atk Arceus Shadow Claw vs. 252 HP / 4 Def Arceus (Ditto): 404-476 (134.6 - 158.6%) -- guaranteed OHKO
The ideal scenario is the one in bold, which will always put the opposing Arceus into range of Liepard's Rocky Helmet or it will knock itself out from Life Orb recoil into Giratina
If Arceus does not terastallize (send in Ditto, then sack Pawmot to see if they do, they should always go for it facing a Ditto, if they didn't go for it the first time then they shouldn't go for it the second time either), then you can send in Ditto and freely terastallize to avoid the incoming Extreme Speed and 2HKO the opposing Arceus with your own Extreme Speed or at least do big damage with the first one and then force it out
If Arceus boosts to +4 and does not terastallize, you don't necessarily need to terastallize either as one Extreme Speed will bring them in range of Rocky Helmet again
If it's EKiller with ESpeed/SD or DD/EQ/Toxic then Giratina's Dragon Tail can phaze it every time it comes in until it's within range of Ditto's +2 Extreme Speed into Liepard's Rocky Helmet
If EKiller without Shadow Claw neglects to boost and instead simply spams Toxic, Ditto will come in and Toxic it, then sack itself off and guarantee one of two scenarios:
A - An opponent other than Arceus is out -> If this happens, spam revives with Liepard to pp stall until they either switch out or get a Bright Powder miss until everything is revived, then sack Pawmot or (if applicable) bring in Shedinja/Giratina to wall them
B - Arceus is out and switched into Toxic, thus getting badly poisoned, if this happens then it's ultimately a game of rock paper scissors, you'll have to spam Protect and try to dance around between Liepard and your Ghost types until they're knocked out, if Giratina is alive in this situation then you'll always bring that in and use Protect, ALWAYS make sure to have at least one Liepard alive at all times
-------------------------------------------------------------------------------------------------------------------------------------------------------------------Mega-Banette can also force 3 attacks EKiller to switch out by alternating between prankster Destiny Bond and slow Thief until it either hits into the DBond or gets knocked out by Thief, the issue here is that Mega-Banette won't be reliable on Assist teams long-term due to the fact that being revived in your mega form is a showdown-exclusive feature and therefore is likely to be removed at some point down the line
Also, non-LO Arceus HAS to boost or it can fail to KO the cat pokemon from 50%, which is what they'll bet at after having been revived:
252+ Atk Arceus Extreme Speed vs. 252 HP / 252+ Def Liepard: 147-174 (44.2 - 52.4%) -- 16.8% chance to 2HKO
252+ Atk Arceus Extreme Speed vs. 252 HP / 252+ Def Meowstic: 117-138 (33.2 - 39.2%) -- 100% chance to 3HKO
-------------------------------------------------------------------------------------------------------------------------------------------------------------------
Glimmora is also an option on these teams but it's even more gimmicky imo since it can't do anything at all besides sacrifice itself to setup Toxic Spikes, which is amazing in some matchups but completely useless in others
Most gimmick teams stop being seen at around 1400-1450, yet myself and others have been able to reach 1600+ with Assist Revival Blessing thus far as seen in the following replays:

Note that winning battles tend to take 100+ turns and aren't down to KOing enemy pokemon, they're usually down to the opponent forfeiting, though Ditto's infinte PP almost always secures a win against non-stall teams that can't break through you and losing battles are often already decided on team preview due to a horrendous matchup such as FIVE Arceus-Normal, all of them with Extreme Speed and Shadow Claw (yes I actually ran into that), making it quite demoralizing to try and ladder up with revive spam Liepard
