Well she can get PhD through LS as well but she might not get the scholarship in that case. Getting a scholarship is only possible in sponsored schemes of HRD/other agencies (with due preference to JRF qualified people). And this is for CSIR UGC NET only. And she should apply for JRF only in the exam (As a JRF is auto considered for LS but an LS cannot apply for JRF).

And clearing GATE will also make her eligible for JRF.
