I think it would need to be a bit more than just that. If you have a Picaso style advertisement for Ford its probably transformative w.r.t. any of Picaso's works since none of them as-is could be used for that advertisement. There's no way Picaso painted any Ford motor vehicles. As well as if you used those imagery as an example of the generative capabilities the originals wouldn't suit that purpose. Or if you had a collection of AI generated art then the originals also wouldn't work.
