I agree that this holds in theory, but in practice? All the overhyping of AI I've heard from the gaming sector has come from the big studios, not indies. And, as you point out, Clair Obscur isn't the 'most indie' of indies anyway.
I don't see the problem because it isn't cutting more artists out of the loop, if anything they get more of the meaningful work
Use AI to automate the boring shit so you can focus on the stuff that matters.
That throwaway texture that's on one model in the tutorial doesn't need days of focused work, so have the AI whip something up. Now your artist has two extra days for key art that's more visible.
