Controlling Ma and Pa would mean that they would look in their eyes, which is something that would never happen with Jiraiya on their side. Even Itachi and Kisame didn't want to fight in combo against Jiraiya and lured him with a girl away... This just shows how powerful the Sannin are.

Sannin would destroy them so hard that the Uchiha Clan would have died out. Itachi could have fought jaraiya alone (not that he would definitely win, but would put up a fight) but they were pretending to attack konoha.
