Up until Jiraiya actually infiltrated Amegakure in his arc, he was still under the notion that Hanzo was leader. All he knew was that Akatsuki's leader was based within the village, not that the Akatsuki leader actually was the leader of the village as well and that Hanzo was already dead. When he even asked about Hanzo in the village, they said not to talk about it and that someone (aka Konan and Pain) killed him off. It wasn't until after that point, during the battle with the Pains, that he realised that Hanzo was dead and that's when everyone else became aware of his passing.
