Jiraiya trained Minato, he knows how he fights better than anyone. He also more likely than not to know how to deal with the Flying Thunder God technique, which really isn't that dangerous if you know what to expect about it. All in all Jiraiya is a much more versatile Shinobi than Minato. He has a much larger breadth of techniques to work with, and much more combat experience. Nor is Jiraiya actually all that slow.
