Ella Bleu Travolta (John Travolta and Kelly Preston's daughter) kind of reminds me of Liv
I don't know if it's because if you see Ella in interviews, she seems to have a sweet shyness to her like a young Liv:

Also, Ella like Liv is really tall. She's said to be about 5'10, which is about the same height that Liv is listed as being.
