The legal right that's been violated is copyright: copies of her work were taken and fed into the ML model... You've stated this very confidently but I see no legal standing for it. Generally copyright infringement concerns itself with the reproduction aspect. Feeding a bunch of images into a model which generates a set of mathematical weights is at worst transformative in nature. Now whether or not the images produced by this model constitute copyright infringement is a different matter.
