The last Captain of the 10th Division was a Shiba, Ukitiake's previous lieutenant was a Shiba, the reason they were able to break into the Seireitei was because of the Shiba launcher!! That is not a bunch of people to be taken lightly given he thought Ganju was a nobody as we know from his words that he thought it was perhaps someone strong hiding his Reiatsu but it wasn't!!

There is no reason to suddenly think that Byakuya is prone to attacking people because he hates their name!! It was declared a war time situation, Ganju had managed to make it to the cell and it was clear he thought it was dumb luck until he revealed his name!! The Shiba are former nobility, and their members have been tough in the past!! If Byakuya thought the invasion was caused by them it is only natural to eliminate the threat!! This is more consistent with his personality, like how he didn't attack Ichigo until he was overwhelming Renji in the Human World or until he had defeated the Lieutenants who had attacked him on the hill!! Going around and attacking people because of he hates a clam is, however, not consistent with his personality!!
