Do either of the captains have a reputation for violence against people who interrupt or eavesdrop on their conversations?

No, they're both quite non-violent but they will make a note. 
Kira might fine you for the offense, citing some obscure clause in an existing agreement.
Orohomi cannot be eavesdropped on if they don't want to be, safe to assume either they want you to hear this or they have deemed you irrelevant to their wider plan. They might be allowing you to eavesdrop purely to use it against you later. The only safe assumption with an elder Vampire is that they are thinking ten steps or as many years ahead.
