She doesn't have the right to wander into our realm and steal our souls. So we went and fought back. That's how wars work...

Besides, it was explained that all of them were originally from the Source. Thus, they are in fact under our jurisdiction.

Our jurisdiction because the Warrior of Light has effectively solidified their position as the most important person on the Source.
Why we do even have to erase them instead of just shutting the system down?
Because she was trying to use the archived data apparently, to create something awful. And she could have potentially tried to make the worst ones appear or something like that. Action needed to be relatively quick to prevent this sort of advantage.
when the fight with Robo-Sphene starts and she talks again about protecting her precious Endless, why couldn't anyone tell her - sorry, lady, we just erased all of them, so you don't have the reason to fight anymore?
I don't think this would have made a difference. It was clarified that this was not really sphene, but her essence. An essence that has a motive that the real version of her may have been more reasonable about. This was actually clarified. What this means is that no matter what you would say to her, she was not going to change course, because she is programmed to do this... even if she has nobody left to protect.
