That's different. Courts have ruled on AI training data as being fair use, but whether you can copyright AI-generated content is another issue.
It's pretty unclear to me where this stands right now. In the USA there are high profile examples of the US copyright office saying purely AI-generated artwork isn't protected by copyright: https://www.theverge.com/news/602096/copyright-office-says-a...
But there's clearly a level of human involvement at which that no longer applies. I'm just not sure if that level has been precisely defined.
