I have to agree with your general statement and core issue. If one is using the more "open to use AI". However apps/tools like https://cascadeur.com/ uses AI to help create animations, which picks from their animation library. However the sourcing of that data I don't know, so it could still fall under the Unethically aspect as I can't say if it's all inhouse/mocap sourced, or they've just pulled freely from anyone and everyone.
But it's possible to have something that provides AI-assistance (from my above example) to things we're more commonly referring to when mentioning "AI" which is your point of "they just use whatever they find, no cares given" with a simple prompt
