Or she's panicking, and not thinking straight. Or she doesn't know that trick. Ren's the only one who uses Aura actively like that, everyone else uses it passively, permeating their body and weapon, yes, but not as a weapon (excepting Semblance, of course); it might be a specialized thing to use it like that. Even so, merely doing probably wouldn't serve as a force-multiplier, it'd just protect the hand; she'd have to pull a Ren to get anything more interesting out of it.
