I think they would avoid doing that at all costs - their defense in court has always been "it's our algorithms", because if they had to admit "it was one of our employees" they would be liable.

There's ongoing antitrust lawsuits about them pushing their own services (e.g. Docs) in front of competitors, and some fuckery with Shopping. Their defense leans heavily on the statement that they didn't do it on purpose or manually, but that their algorithm considers their services the best. For that they need to lift the veil a bit on their algorithms (and iirc there is an outstanding court order for that one already).
