the LITAVR interceptor drone could lock onto a target by itself during the final stage of flight

Sounds like a classic ramming. I think drones are still too battery-constrained to become reusable.

Good question, I can't find any specific information on how the Cyclops intercepts drones which could be a simple translation issue or it could indicate that this is far more than just a guided munition...

I guess the big differentiator in design that would answer that is are these designed to be recoverable?
