The fact that models creators assert that they are protectrd by copyright and offer licenses does not mean:

(1) That they are actually protected by copyright in the first place, or

(2) That the particular act described does not fall into an exception to copyright like fair use, exactly as many model creators assert that the exact same act done with the materials models are trained on does, rendering the restrictions of the license offered moot for that purpose.
