Since itachi has the intent to capture, he'd have to use a non fatal Tsukiyomi in order to put Bee into a minor coma or just knock him unconscious. Bee is no idiot and would probably avoid eye contact but Itachi will definitely be able to trick Bee into a Tsukiyomi. Sure Bee will eventually break out since he is a perfect jinchuriki but despite this, the Itachi's Tsukiyomi is on such a high level that Bee will still get hit badly.
In this fight, Itachi will be doing all sorts of tricks in order to tempt Killer Bee into looking into his eyes. Bee is very carefree and will eventually fall for Itachi's tricks. The problem is that Itachi can't use amaterasu against Bee or else he auto loses since his intent is to capture. Although he could still use it to weaken Killer Bee although then Itachi would have to extinguish those flames which would further put strain on his eyes and body something that Itachi can not afford to do.
Bee with his V2 cloak is incredibly fast at which point Itachi will need to use susanoo. It depends on how long Itachi can maintain susanoo although even without it, through the use of crow clones, he can trick Bee into a minor genjutsu only to be put into a tsukiyomi later on.
Itachi wins mid-high difficulty and +rep for interesting match.
