She was not the one who made it, it was another guy Jack with another dude, she was part of it, but it was not her thing like the older books.
There is no way to know how much hand she had on it, but i read before it was minimal, which makes sense because it have nothing to do with the story she did anyway. like bringing back the devices that turn back time, when she was the one who destroyed all of then because of how problematic it was to the story
