Vincent's alchemy requires some form of preparation;none of Jason's powers require any of that. Jason also has a strong mind, due to other mental penetrations by his patron, Athena. He's quite adept at repelling/ resisting mental effects. If hee needed to, Jason would plea to Athena to strengthen his mind and help him resist Vincent's alchemy. And Jason's weapons were made by Hepheastus  himself. They were made for a god; no mere alchemy could destroy them.

And Jason has fought gods; he's fought Athena herself and survived. He's used to fighting unpredictable people.

If Vincent would not engage Jason in manly combat, Jason would just use his powers. It would be very hard for Vincent to concentrate when he's being blown around by a category 5 hurricane and shaken by a 7.0 earthquake...or worse, if Jason can trigger himself into Glowing Sea mode. Which isn't too hard, considering all the times he's seen his friends getting hurt. If he were to enter that state, there would be no limit to the damage Jason could do with his powers.
