Spreadsheet time!
(It worked for DDs medicine application, but should also work for other subjects.)
Get a list of philosophy departments and paste them into Excel. Delete those whose entry grades are too high or too low. Delete those whose locations really don't appeal. Campus or City? Accommodation options and cost? How far from home? Other stuff: good hockey team; lots of drama; party reputation?
That should make it manageable.
Then think about what interests her most. Is it logic and maths, or politics etc and look at the courses. What courses are compulsory in the first and second years. What options are available, including outside options. This should narrow it down a bit. If you don't like maths you really don't want to be taking a maths and philosophy type course, whilst she might find some offer some great options (study abroad?).
Then look at staff within the department. What have they published. Are these the sort of things you would like to read? (If you find a whole lot of gender bollocks, then rule them out.) Being taught by a leader in a field which interests you is fun.
Or a bit left field, but if she is interested in feminist thought, Dr Jane Clare Jones both offers courses in feminist thought feminist-institute.org/ and does some tutoring. (I am tempted to ask DH to buy the course for me for Christmas. I am a JCJ fangirl.) When my DS was doing his Masters, economics not philosophy, he got paid via a tutor agency for helping a first year UG, almost certainly an overseas student, with options choices. It struck me as a good idea, in that it would be useful to know which courses were useful for future years, which were well taught and fun, etc. Would it be possible to identify someone within the area that interests her most and who knows the higher education landscape who might, for the equivalent of a tutoring fee, take her through the pros and cons of her preferred courses.
