There's also stuff like server intro guides and onboarding steps that should deal with most of the low-hanging questions... Should, but don't always :P
As for use of LLMs... probably an interesting use-case, but I'm not aware of any solutions using that quite yet.
My anecdotal data is based on observations from my partner who has boughten several asset packs from itch.io, got on the discord for support, and the artists/game devs have been extremely unwelcoming to the point of just banning users for simple game dev questions and/or mentions of AI.
Of course, gamers (competitive) are generally a toxic bunch.
This is understandable when you realize that artist are being accused of using AI for every single imperfection in art now. You messed up on perspective? You must be using AI. Anatomy is slightly off? You must be using AI. At a certain point they just get tired of the accusations and choose to ban people.
