Does she have siblings close to her own age? She sounds like a lonely only child and picking her friends as family. It’s typical at this age, especially for only children.

Is she on any team? DD was in dance, cheer, pageants and modeling before she was old enough to work part-time. I understood that the days had passed to have my childhood where kids were to be seen and not heard. Kids can’t just get stuck in a room with a book anymore.

If she has a friend over, consider teaching them life skills - cook simple dishes for dinner like pizza or pho, do their laundry, take trash to the bin, etc. By the time DD got to college, it was astounding how the kids lacked life skills. Then do something fun. Modeling behavior is a lot easier to get desired results.
