"And if Ruby still had Aura left, the stinger wouldn't be able to pierce her."

Ahem....Adam pierced Blake when she still had some Aura left.

"And if his blows can disrupt someone's Aura"

Mega assumption.

"this isn't Torchwick she's dealing with, not even remotely close."

But, he was supposed to not kill her. And if she had no Aura left, given the speed of the stab and the strength of that tail (enough to hold back buffed Nora like nothing), then he would indeed have killed her, venom or not.
