Quoting Mother of Broccoli.:" I ignore her when she is tantruming. When she's done I give her lots of positive attention, like hugging, ... [snip!] ... kissing, cuddling, etc. I do redirect her but it has gotten tiresome lately since she wants what she wants, when she wants. "
I guess I meant to say beforehand are you washing the dishes, reading a book or are you two just playing together?
It sounds like you are doing all the things you can do, she may just need a few more months before she can be more verbal and you two can talk about the actions.
Edit: Sometimes just picking her up and going to a calm space gently telling her we do not throw toys and we are going to sit here and have calm time focus on breaths if she is freaking out then reading a book or two is always a good option for a non-punitive time out
