No biggie to me, either. Shade can fill in what he prefers.
"Him" selects Ability Focus.

The flavor text seems to indicate some degree of parley, so Diplomacy and Sense Motive might be appropriate.
For the skills, how about...
Appraise 18, Diplomacy 18, Knowledge (history) 18, Knowledge (religion) 18, Knowledge (the planes) 18, Search 18, Sense Motive 18, Spot 18, Tumble 18
...with a note in the Spelljammer Underbar that they replace Knowledge (the planes) with Knowledge (space) in that setting?
These don't really seem like they'd have treasure, do they? The original has treasure nil.
Blazozoids usually ignore passing spelljammer ships unless bothered in some way. However, blazozoids do approach ships when they want one of two things: either a ride through the phlogiston or a meal. If the party refuses to give the blazozoid a ride, or if it is searching for a meal, it attacks.
So I could settle for true neutral to avoid a long argument, but CN sound like the original designers just made a mistake. The only way they'd make sense as CN is if there's something in the description of "I" that clearly sounds chaotic.
I'm in favor of true neutral barring strong reasoning from "I" as well.
