I think with "No, Totally" in particular, the "no" is refuting something implied. So with "Makes you want to hit them", you are instinctively saying "no" the cultural prohibition against violence. "No that's not normal behavior, but yeah, totally I want to hit them." For "Would you like ice cream?" you'd say "Totally" because the connotation is good. "Don't you just want to eat the whole tub of ice cream" -- "no, totally", is a reasonable response because you're resisting the negative connotation of pigging out. I think this is actually unrelated to the "Yeah, No" phenomenon.
