The latter might be feasible (Though I doubt databrokers will let the current laissez-faire data-rights landscape go without a fight). The former is both wrong and infeasible.

Bigger models get better at copying style with fewer examples. At some point, it'll be enough for a big model to see sufficiently few examples of real people drawing, "X in the style of Y" to get a sense for how to draw a thing in the style of Y.

Or an end-user could just feed a single instance of parody art in some artists style, ask for variations, in-paint what they want, and voila! Copyright free [citation needed] style transfer.

It will always be possible to launder style, even while adhering to promises to never touch an artists work (directly). Training on an artists entire body of work is not the only way (and thanks to copyright, a not even desirable) way to do so. edit: Open source models will also mean blacklists are unworkable.
