Pokemon Legends: Arceus will not have any influence on Sword & Shield OverUsed.
There is no known transferability of the Pokemon exclusive to PLA to Pokemon Sword & Shield. While this has the potential to change in the future with Pokemon Home compatibility, Sword & Shield OU, as well as its respective lower tiers, will not be impacted in any way upon its release. For information regarding their eligibility with the National Dex format, an unofficial metagame which maintains the main series' stripped mechanics and Pokemon from Sword & Shield, please read this thread.
The SS OU moderation team wishes you a fantastic weekend, and hopes you will all enjoy the new release!
