You forget Hidan can heal.

"Mere moments after that battle he had been completely healed from all of his wounds and the damages he was subjected to such as getting his rib cage crushed by two kunai blades,[19] piercing his leg,[20] getting his whole body perforated by Shikamaru's shadow,[21] stabbing his chest with his retractable spear,[22] having his scythe piercing his abdomen and go through his back,[23] and getting his neck sliced then reattached."

That doesn't sound any less serious than the beating you'd get from a Gate user. Lee can only go 6th Gate so he can't dish out any damage that would keep Hidan down. Yeah Hidan couldn't possibly keep up once Lee uses the Gates but all that would happen is Rock Lee would beat the shit out of Hidan till his Gates incapacitate him and then Hidan would get back up and kill him.
