We've been shown almost a dozen instances of Luffy and Kaido using AdCoC... And Yamato using it too. None of them have smoke coming off of them while using it.
But you are taking one single scene where it clearly looks like Luffy is blocking a Boro Breath, and trying to use that one singular scene, where its not even 100 percent certain what is happening, to try and act like smoke coming off of someone is the normal while using AdCoC.

But i get pretending he chose to stand still and take an attack suits your agenda more.
