It's pretty annoying to watch Akira act like a fool all the time, but on the other hand, it should make the enemies to look down on him. It's pretty clear Pansylvania, in general, doesn't give a shit about this group of people from Stromheim. Pansylvania is hiding a deep Singularity/Oder connection, by the looks of it, but they totally expect the Medis/Akira group to discovered nothing of any use during their stay. Akira behaving like a dimwit must only reinforce that impression. He's not doing it on purpose, he really is like that, but it does serve its purpose. Pansylvania only accepted this visit due to wanting to gauge Akira and learn more about him, but if Akira's character actually was something like duke Cold's, would Pansylvania have taken the risk?
