It could be worse. Many kids gravitate towards the picture-perfect uber-expensive schools and are unwilling to consider pragmatic, quality, in-state options that are affordable!
As others have said, I’d back off for awhile. Some kids genuinely don’t have strong preferences and would be fine anywhere. And as somebody else mentioned upthread, your child may be anxious about entering adulthood and just doesn’t want to deal right now. I bet as her peers become more invested in the process, she will too. If her HS offers more hands-on college counseling, that will also bring her on board.
