Danzo was the first to guess that he was dead after he stopped receiving secret correspondence from him. That's true in the manga as well, since Jiraiya was surprised to learn he was dead when he infiltrated Ame. But I think that filler had Konan or Pain say that Oboro's team were sent to the exams under Hanzō's rule. Doesn't make much sense for Pain to have been screwing around for more than a decade while Hanzō remained in control though.

Edit: Just checked the episode. Konan says that Hanzō sent several genin teams to the previous chūnin exams (Part 1). So apparently the Amegakure civil war, or at least Pain's victory, took place during the month between the preliminaries and the finals. Or Studio Pierrot just forgot about that.
