Hiraishin means he doesn't have to bother with summons. He can simply bypass such attacks and keep the focus on Jiraiya. That's the biggest threat to Jiraiya, that his usual defense methods to enter Sage Mode can be relatively easily bypassed with that jutsu. Even with toad mouth binds and other similar jutsu, he can keep the fight on Jiraiya.
