Celebrities have some right to publicity, so in this case she could argue that they were watering down the value of her as an actress by widely selling an unauthorized sound-alike. The laws around this aren't strong (which is why her response pointed out the need for legislation), and as I mentioned OpenAI would have been in a much stronger position if they didn't directly reference the film publicly several times. One could argue that they were using the film and her role to promote their product.
