Is it possible to trick a LLM into not knowing what something looks like anymore?

Say I’m a car brand or any other product maker, and I don’t want people to generate AI images with one of my models in it. Would there be a technical way to make a LLM not know what the model looks like anymore? Like creating a website or database filled with -say- dinosaur images named like your car model, that would confuse the generator?

I’m not looking for the “Have your lawyer send a cease and desist so they ban the term”, I’m looking for the creative route.
