As you can see from the responses, the advice is all over the place. Not every kid comes home from freshman year with a job. She should certainly be looking - even a camp job might still be available. The initial we’re all back from college, let’s hang out and party scene may fade a bit as kids get jobs and need to be home at a reasonable hour, although 11:30 may be a bit early even during the week.
You are on the right track in terms of meeting with the therapist as a family and having her go as an individual. You need to pick your battles to some extent and give a bit since she is an adult. What are your goals? I would guess the primary one is to ensure she is not partying excessively and is ready to be a better student next fall. I would also think doing something this summer (if she can’t find a job, perhaps a class at a local college since she is on a reduced schedule) would be an option, depending on finances. If there are substance abuse issues, that should be the key focus.
