chances of a stat correction is likely larger than the odds of Etienne going negative on points. Especially considering the small margin.
if we ignore the moral high ground for one moment, from a mathematical perspective for me to even consider benching the player the margin of victory would need to be more than 1 point. it is not often that a stat correction is much larger than this. if you look at the stat corrections your fantasy league has, most of your stat corrections are less than a half point. (usually a run/catch credited for 6 yards gets changed to 5 yards upon review) They can be larger but its incredibly rare. As your margin of victory if you sit him is 0.2 of a point, I do think (if you ignore the morality of the move) the right call is to play him anyways. if your margin of victory was a bit higher than this (say 1.7 of a point) that would be enough to account for 1 reception in PPR with yardage of 7 yards on the catch or 17 total yards on a run or 34 yards on a pass. At that point, I'd suggest the odds of the negative points due to a fumble etc may be greater than the odds of a stat correction large enough to alter your outcome. I cannot say for sure but it would be close.
I also agree with a prior poster, this is really more of an issue if your last remaining player to start is your defense as defenses can give up negative points in high scoring games. Dallas got me -1 points this week.
but with a bellcow back? odds are likely in the range of 0.001% or something of the like. Certainly not zero. but probably something you can live with.
