It's called making time. If they are fighting in a forest, surely Jiraiya can run and set up the seal at the same time. The way you all keep talking, you act like it's completely impossible. Depending on your approach, anything is possible in Naruto, even using this seal when taking cover. Sure, it doesn't have to but set up in one go, but can be set up in parts. Either way, it's completely possible under the right circumstances. It's not like they are all fighting in a massive desert when they can both see one another constantly, they are fighting in a forest, where one can hide some someone else. Locations play a BIG role in fights, just look at Jiraiya vs Pain and the industrial environment.

And if you want to get technical, in 3 panels, he wrote out the sealing formula and performed the handsign to seal the flames. That's a way faster than you all think it is.
