Who dealt the killing blow is irrelevant. Kaguya's entire purpose, at least to anyone who was not grasping for straws mind you, was that Madara got way way to strong and we needed a villain who could 1) take him down quickly and 2) have such a clear weakness that they could be handled in less than 20 or so chapters.

And that was Kaguya in a nutshell.

Also don't get Elvenora started with that. Seriously.
