For me the discussion of whether someone who lost all his mental capacities could use the physical manifestation of a mental ability seems redundant, and has been discussed to death.
You make a fair point regarding Killer having not shown CoA though.
One might claim the way Zoro was handled in that scene underlines his lack of good CoO and speed in the first place.

Just that Killer not using COO or COA (the basic version) is kinda unsubstantiated imo. I don't rate Killer by his showings as Kamazou but it's not like he completely switched of all forms of Haki even basic ones in that fight.
