Hear it in context
Notice where the phrase sounds natural.
We met at a party and just hit it off straight away.
A: So how was the date?
B: Really good — we hit it off right away.
Fix the pattern
One small grammar move makes it sound right.
Not: We hit off really well.
Say: We hit it off really well.
Keep the 'it': it's a fixed phrase, 'hit it off', never 'hit off'.
