I understand what you're trying to convey, but the problem is that Renet herself couldn't exist to tell the Turtles anything if the MA storyline happened. She's human, and we're explicitly told that there are no humans left for her to be descended from, let alone a society with enough potential resources to create time travel. There's also no suggestion that she somehow blinked human civilization out of existence through any accidental actions.

You can only tackle the butterfly effect and the fluidity of time if you keep track of how the ripples are actually going to go and what will happen to them, and this just sets up a massive paradox wherein her intervention was required for the Turtles to exist at all. Previous episodes established that things that happened in the past have "always" been that way, fated to be if you prefer.

As for the question of whether her intervention somehow caused MA, I didn't see any evidence in-universe to support this idea. It seemed more like ignoring past established canon than building off parts of it. It is an interesting idea, but I don't think it was on their minds, personally.
