This is so vague in practice. The only thing I can see working out is banning creators who are so obvious with their use of AI that they directly forward watermarked content to the platform and we can establish cryptographic guarantees that the content was generated entirely on a GPU farm. Everything in-between seems to me to be extremely fair game for the problem of music production. We can hold our nuanced debates about what constitutes "AI generated" while listening to some minimal EDM tracks to remind ourselves how fine a line we must walk.
