Zoro won't be controlled but there's a possibility Sanji will be. Oda kind of set this up back during Wano when Sanji told Zoro to take him out if he ever lose control and become evil. Zoro vs Domi Sanji would be the perfect opportunity for Zoro master ACoC haki and improve his shockwave attacks.
We all know Zoro won't kill Sanji so that means Zoro will need to hold back. Until Zoro can recognize his CoC haki and consciously control it, the battle will be harder because he's not going to want to accidentally use CoC haki against Sanji and kill him. He will need to master that power to properly fight Sanji.
Even without CoC haki, Zoro's cutting power is deadly and incredibly powerful thanks to his powerful CoA. Cutting attacks would probably be too risky to use against Sanji. That would force him to use shockwave attacks. That would be the perfect attack against Sanji for that situation. It would damage him enough and send him flying away without killing him. That would give them time to deal with Imu, HKs, and figure out how to counter Domi.
Zoro has shockwave attacks unfortunately a lot of his shockwave attacks also contain cutting power so he would be limited to just shockwave only attacks. He would need to create some more and improve his strength in that area.
