I can’t leave her in a room alone with anyone for fear of her hurting them etc…
I know it's sad. But that would be a dealbreaker for me!! At the age of 2, with her being around your rules for almost half a year; you should not still be dealing with this. And no daycare child is allowed to hit or kick me, or anyone else for that matter.
I hope you manage to fill that spot with a lovely family, soon!
