The "Italian WWII genre" doesn't actually exists (just some B-movies set during WWII, that's it).
Since even those movies are unknown, there isn't that much to "spoof", beside the "pulp" feel of B-series productions (of which uncle Q is found of). So the "intentional" part could be applied to the over-the-top/campy style, but the issue with the italian dialogue I mentioned is a typical hollywood oversight (at least this time they tried before failing).
