There is no psn requirement for this game (on the gog version at least)

It requests it but doesn't require it. True, you need to select "limited" or "full" but you could just disable the network or firewall it. I run it in a container without networking on linux mint and it works perfectly.

I'm running the gog version through wine with disabled networking for that container and it works perfectly. I forgot that the game has a telemetry option until I read this. Pick it up on gog, it goes for ~10€ every time they have a sale.
