Wait, what new game engine are we talking about? Was it the one which happened like 30 seasons back which boosted OD to stop everyone from running outside offenses or something? I don't really remember 2-3 being any good for a very very long time tho.
Iirc playing 2-3 against LI used to result in your opponent's guards driving into the paint. I'm not to sure how it works anymore nowadays tho (not sure if there were any changes).
That said, I'd usually go with 3-2 against LI. In fact it seems to be a good choice to run it against most offenses unless you got a balanced team (which I currently don't have, sadly), then you can use M2M.
