Honestly, it's not really valid to say "That's not chibi, this is" to something that's hard to translate into chibi (like a starfighter) using something that's very animal-like and therefor easy to make chibi (like an AT-AT). The idea to make them chibi is rather convoluted due to there not being much precedent and the rules don't really make it much clearer, simply saying to make the ship small and "super-deformed" and the only person to delve deeper into that meaning was Legomancer, saying

which is what all the current entries have done.
I'm guessing that for examples of chibi ships, you want something like Hasbro's Galactic Heroes line like these: X-Wing and SnowspeederMillennium FalconRepublic Y-WingJedi StarfighterSlave 1
