She seems incredibly awkward (I), seems to express herself through hands, sounds and active actions (Se). Rambles a bit and doesn't seem to have a lot of structure to her words (Te expressing Fi). Often said to get caught up in the moment in her performances . Heavily concerned and focused to the person in front of her - almost never seems to have to process and go inside of herself that could imply Se and I think the way she kind of process/words her arguments may imply Te over Ti. Her loud outfits make me think Fi over Fe. This is just a surface analysis, open to other opinions. First impression though I think ISFP may be it. She's been said to be a sensitive free spirit who was bogged down from her baptist upbringing that seems Fi too to me.
I'd guess ISFP, maybe ESFP. She seemed like an introvert in some ways who sometimes got into an extroverted character in public or on stage. I know she was very self-conscious & insecure all her life & often had her guard up & that makes it hard to read her. I wonder how she would have come off one on one, might be different, I don't know.
