I'm going to answer this differently, as someone who went to college back when it was a "must do," and dropped out because of being in too general a field. What would have been best for me would have been the "gap" year that I wanted to take to travel. Attending the required first year college curriculum might not stir up any more interest in her as the subjects are pretty basic - she many not really be exposed to any careers, trades or subjects that do entice her, unless she samples from each major. I did that as well, and it was a huge waste of time and money.
What's important is that she figures out what does interest her. If she took a gap year, she could get a job and see what it feels like to earn a paycheck. While may not be an option for a long term career, it can help kindle a love of working and serious reflection on career choices. Does she have a guidance counselor? She should start doing some research on different industries and fields.
Finally, if you do decide to send her to college, you may want to put a limit on how long you'll finance it. You don't want her to be there 3 years with no clear major, or flip flopping major choices every few months. That will only extend her attendance with no real result and encourage her postponement of making a choice. (I'm speaking from experience.) If she does attend, she should talk to the heads of different major departments to find out what opportunities exist in that field. Many of them are happy to talk about their own passion for their subject. She can also do that without attending by making appointments and attending information nights. I hope this helps!
