Even if he could not see the future he would see himself getting killed so he will skip the time. Nope, the future seen by Epitaph is impossible to avoid (save by GER shenanigans I won't be discussing here). Don't you remember Diavolo telling Doppio it was impossible for him to avoid the damage he was going to receive from Risotto in any way? Don't you remember he foresaw his hand was going to be pierced by GER and was unable to do anything about that?

Time skip + Epitaph is only useful to reach an otherwise impossible future (he sees himself backstabbing an enemy that's on guard in front of him: he has to erase his perception of time to allow that to become a reality).

In fewer words if Diavolo sees himself being stabbed by The World's hand he's already lost the battle.

To conclude, Diavolo is still vulnerable to stealth attacks, he was trapped inside Coco Jumbo's clone without even realizing and he was punched by Sticky Fingers. He couldn't even avoid Bruno from escaping with Trish. He's not using Epitaph 24/7.

By the time part 6 happens, Jotaro is back at his prime (5 seconds) and thus is said to have the "strongest stand ability ever" and to be invincible as well.

However given that you mentioned only the anime I'd say you are half-right since Jotaro hadn't regained his full domain of time stop yet but DIO should have the honours instead (The affirmation about Jotaro in part 6 is about his ability, DIO had the same ability and could manipulate it to an even higher degree).
