I think I phrased it in a confusing way. They care about your solution in the sense that they want to know if/how you'll solve the problem. They don't care in the sense that they aren't trying to learn the answer by interviewing you. It's not like they have a critical red-black tree problem and they called you in to fix things for them. They know the solution so the existence of an additional out-of-interview way to get to the solution like a language model doesn't change anything about the usefulness of the interview.
