No way you could use a neo as a livestock guardian, and I think trying to train it to be one would be borderline animal cruelty. Most dogs are overwhelmingly drawn to people, neos maybe more than any other, a livestock guardian needs to be ok with hanging out with alpacas(or whatever) all day. A neo just isn't going to do that. Mind you, if your alpacas don't range very far from your house any dog would serve as a "livestock guardian", just by guarding the house and area close to it. But if you want a dog to follow livestock out into the sticks and stay with them, you'd need a real livestock guardian.
