LitZ is honestly not very hard to get to if you focus on that, assuming the machine isn't too hard. Focusing on LiTZ is just not a good strategy for getting high scores, since it only pulls like 300-some million, which is poor payback considering what you need to do to get it.
It's 29 shots, 43 if you avoid the slot. (subtract 2 for each door panel you spot, 3 if you are avoiding the slot, so 27 or 40 if you make the skillshot).
Certainly a much easier proposition than on most games.
I don't have 9.4H yet, and can't see myself using the LiTZ mode myself, maybe to surprise people...
