I can't believe that people who use the physical medium of paint on cement, who are about art by people for people in the most tactile way, would knowingly and willingly use AI. But one of my editing clients had obtained bunches of quotes from famous people, using AI to collect them, and several of the quotes were pure fabrications. They sounded very like something the person had said, but they had never said it. (Or at least, it wasn't a genuine famous quote by the person; obviously I and the internet at large can't guarantee that, for example, Mary Oliver never said X,Y,Z but we can tell it's not a genuine widely know quote with an identifiable original location.)

The Emily Dickinson lines they quote are very Emily Dickinson-esque, but almost too pat? So that's why I worry.

But it's also possible they merely misattributed, or that someone somewhere--maybe they themselves--did an idiosyncratic translation, etc. I'd prefer that to be the explanation.
