There is nothing that would suggest, that she was capable of using any other kind of Force power in that scale. And, as Kylo Ren has shown, there is a possibility that she might be a defeseless without a lightsabers.
Is there a reason she wouldn't be able to just TK them? She was pulling down a starship before the amp. She can shoot lightning too.
