This paradox is present in every time travel story in which someone tries to change something in the past, and it's easily explainable: whatever that someone is trying to change cannot be changed. If someone's actions in the past somehow prevents them from being born, they will have been unable to travel into the past in the first place because they don't exist.

It ultimately didn't matter what Starlight was trying to accomplish because it already happened. Her traveling into the past in the first place means the rainboom was unpreventable.
