How is that useless? You adding the warning tells me everything I need to know.
Either you generated it with AI, in which case I can happily skip it, or you _don't know_ if AI was used, in which case you clearly don't care about what you produce, and I can skip it.
The only concern then is people who use AI and don't apply this warning, but given how easy it is to identify AI generated materials you just have to have a good '1-strike' rule and be judicious with the ban hammer.
