To be honest my technique for relatively pain free AI eye neutering, learned the heard way when that bug with turtles was in the game, is
(a) send in a sacrificial force of maybe 40 to 80 or so ships to draw in the AI fleets.
(b) Once those have got the computers attention send in a full cap of raid starships to run around and kill the guard posts. You can also use teleport raiders for this, but that will almost certainly trigger the eye
(c) if there is Spire Shield posts then you can kill the command center and take the system. The spire shield posts will self destruct once the system is yours, as will any stealth guard posts.
Bear in mind that this will set free all the ships on the planet, so you have to be prepared for that.
