Well, if you think about it, The Knight isn't completely, entirely hollow. They have the mind to have knowledge of wielding the nail and basic movement (plus all the other abilities). They have the memory capacity to remember everything they learned (nail arts, abilities, quest objectives, names, etc.). And most evidently, the will to choose when and where to use them, and also all the marketing stuff.

A couple (literally) of things even says this, like Jinn's dialogue when you refuse to trade Geo for egg, and Voidheart's description.

So yeah, not 100% hollow, but hollow enough to put Hallownest into another stasis, should they decide (with their will) to just contain the Infection.
