Maybe in this story Jiraya helped the trio earlier, but it doesn't make much sense for the Protagonist to know that since he's basing his knowledge of his world on Naruto's story. In the original Jiraya is only in the rain village to fight in the war, with Iwa already in the conflict. Then he sympathizes with the children and stays to teach them. But at the time of the fic Iwa hasn't entered the war yet, so it doesn't make sense for the kids to know Jiraya and like I said, if Jiraya helped the kids before what is described in Naruto, it doesn't make sense for the Protagonist to know that. But I thank you for writing
