Zetsu clearly reacted to Susano. It was "what-" that was stated. The key element is "-" which indicates he was not done saying what he was going to say. Then he completes what he was going to say, saying "what is that" referring to Susano. Zetsu did not react to Itachi being alive. The fact he even asked if he died, says he had doubts he died.

I can see your point of view and it's a good point. However, the step by step process happened extremely fast. SO we wouldn't see Zetsu react until it was time for him to react. All Itachi had to do was activate Susano as Sasuke moved his arms and spoke. We wouldn't see a reaction from anyone at that point since Kirin strikes fast (possibly) and strikes immediately after he's done. Therefore, Itachi could've activated Susano right before Kirin made it's descend in response of what Sasuke told him and did.
