I think the confusion comes from the fact that the speed at which smth manifests into existence, at least in the case of Judgement is literally infinite. In-game, Helltaker couldn't dodge it since the chain is summoned already wrapped around him via Judgement thinking it. Obviously in a case where someone is significantly faster than Judgement, they can "dodge it" by simply being too fast for her to see them or think about summoning it. But in a normal situation, where the two are equal, how could they dodge it if there's no indicator it will appear around them, and spawns into existence already wrapped around them tightly? Unless you have TP of course, in which case you can just TP out after being restrained.
