No need for hollow points as they would never expand at these low velocities (even the softer lead doesn't anyway, unless it's against soap bars or ballistic gel)
The hollow point fulfills 2 functions
Firstly in terms of sub12 slugs, it allows the overall weight to be reduced, from what would otherwise be a prohibitive weight. Done properly, it doesn't affect flight or accuracy.
Secondly, the expansion. I can assure you that expansion happens at sub12 velocities in .177

I can't comment on .22 slugs as I haven't tried them
