It shouldn't belong to the AI, it should be its own faction and as a unit, it isn't claimed by you or the AI. It just checks who the current owner of the planet is. If you deliberately destroy it then it generates a burst of AIP, but then does nothing else for the rest of the game (so if you wanted to raid the AI and just destroy them, you can). The difference is that on the hour mark instead of generating X AIP (where X is the number of seeded risk analyzers), it should generate (X - <number of Risk Analyzers you've captured>) - 3 *<number of Risk Analyzers you've captured>.
The above is pretty much exactly the AIWC behaviour (except that in AIWC killing a Spire Civilian Leader did nothing).
