Interestingly enough, it's far from difficult to remove the lactose from cheese, and in fact it's often done and thus many lactose intolerant people can have cheese. A better question would be, would an alien be lactose tolerant or intolerant? I think it would most likely be lactose indifferent, although I suppose lactose intolerance is more likely than lactose tolerance since most humans aren't even lactose tolerant (beyond infancy).
