I'm thinking of "space roombas" that glide around and bump all the sats in LEO into the atmosphere like a game of pool

Only problem is they are toxic as they burn up and create a lot of pollution

(too bad gravity is impossible to overcome cheaply or do the opposite and yeet into sun)

If you have to yeet space trash to a gravitational well, Jupiter is probably the more attractive option. Lower delta-V, still a large well, and so long as you get reasonably close, orbital decay should solve the problem eventually.

For de-orbiting LEO satellites, electrodynamic tethers is probably the most viable active method:
