The author of this website, Blake Esselstyn, presents the case for a new term to describe content that is free of AI. There is a fairly comprehensive rationale and definition of terms that I think is defensible and certainly reasonable. I'm not sure how it will land here or what kind of traction it will ultimately get, but I'm sure people here will find the discussion worthwhile.

How does "zuzai uses zero AI" fix the organic vs pesticide free metric?

The only difference between it and "AI-Free," "no-AI," "non-AI," and "not by AI" is that you're using more words to say exactly the same thing. 'zai' -. "zero AI" would be precisely the same.

Author has pointed out an issue that the phrase carries just as much as "pesticide free" would in their own estimation, and simply jazz hands away the fact that the proposal is susceptible to exactly said critique. AND, I'd argue that both 'pesticide-free' and 'zero-AI' are better specifically because they draw attention to the issues caused by pesticides and AI.
