Any autonomous mechanical devices are forbidden (sparring bot is described as dangerously close to thinking machine according to law and religion (IIRC). Butlerian Jihad took care of that.

So teleoperated - which means short range (if any), as signal jamming would be employed. Don't remember though if there's mention of jamming.

Drone with lasgun necessarily will be big and bulky, thus easy to destroy. Unless shielded, but then will be a risk to the launcher.

And last - there is a mention that both lasgun and shield are destroyed in atomic annihilation (or something to that effect), so shooter gets the same treatment as the shield protected target. So this would be a case of Mexican standoff (range) weapon.
