And also since the hollow Ichigo was technically the physical manifestation of Zangutsu (he took over Ichigo's body completely) wouldn't that technically mean that Ulqiorra was in fact killed by a zanpaktuo? And yes I understand that the hollow Ichigo was holding Zangetsu in his hand but at that point it was just an extension of his arm. Alos Kubo has made it a fact that Ichigo and Zangetsu are both one being. In the thousand year blood war arc when Ichigo gets Zangetsu reforged he says he will no longer ask zangetsu for power instead he will us his own. He then says thank you to zangetsu as a way of saying "Thank you for showing me that you and I are one and the same, your power is my power and vice versa."
