I would just lay off of it and continue to stock her with books you think she'd enjoy and cut out family reading time if the books are intolerable to you. I haven't been allowed to read to my DD since she was 5. She found reading aloud too slow once she could read well silently. I was pretty sad about it, but it is what it is.
It sounds like you've gotten into a power struggle--believe me, I know allllll about it--and when this happens here I try to disengage. I don't think this is a hill to die on.
