Sounds like she may be modeled after a comics character named Alexandra Allston (Parasite).

I'm not quite seeing the full connection so far, but we all know that the Arrowverse has drawn some rather interesting new interpretations from existing DC comics characters before...

Was Ally Allston and her cult a reference to Allison Mack and her membership in a cult?
