Pretty much subject line. The official FAQ here states that you are not making an AOO: https://paizo.com/paizo/faq/v5748nruor1fn#v5748eaic9uws
Does this then mean that bodyguard can be used while taking the total defense action? I have found a previous post from Jason Nelson (the author of that feat) that says you cannot but it was about 4 years before the FAQ was issued. I could see an argument being made for "your AOO pool is not available when taking total defense" I guess?
Some clarity on this would be rad.
