Answer
In the DC Animated Movie Universe (DCAMU), Will Smith's portrayal of Deadshot in "Suicide Squad" is not the voice behind the character. Instead, it is Michael Rosenbaum who voices Deadshot in this animated universe, appearing in several DC animated films such as "Justice League: The Flashpoint Paradox" and "Batman: Arkham City." Rosenbaum's voice acting brings a unique interpretation to the character, distinct from Smith's live-action portrayal.
