Depends upon what you mean as “official” and what you mean by “commentary.”
If by “official” you mean promulgated by edict of either a council or pope (vis-à-vis the various “departments” of the Curia)…then, no, there is not.
Many Catholic universities & publishers produce “Catholic” commentaries…but they are by no means “official.” Some people mistake an Imprimatur the editors obtained as making it “official.” This also includes commentaries written by prominent Bishops, both past & present.
The better word should rather be “authoritative.”
As far as what you mean by “commentary”: there are all sorts of types of commentaries (scholarly; pastoral/homiletical; spiritual, etc.).
I think the closest you’ll get to an official commentary would be the CCC. Utilize the Scripture cross-refence index.
