She's undead. She already has infinite "vitality" (necrality? thanatality?), no matter how much you wound most undead you'd never do more than slow them down, particularly with necromantic support. The Ochimusha needs the support of her husband, who would be significantly weaker than her and thus a high-priority target and who would be unlikely to be on the battlefield alongside her, limiting her ability to regenerate until she can retreat and recouperate. She's not described to have any physical resistance to damage, which puts her durability below quite a few other monsters.

Further... it's always been well established that humans are below the monsters in both natural ability and the limits to which their power can grow. Ochimusha were already veteran warriors before death, and even if they were brought back as a less powerful undead then they'd still be far beyond what a human of equal skill would be capable of matching.

Leaving all that aside, though, KC has said before that the Monsterpedia entries are created in-universe and aren't object, and some can have a degree of hyperbole (usually when regarding absolute statements). So it is most likely that there is a point after which her body simply completely fail. It would probably be something ridiculously extreme, though.
