Shotgunjones
I have been at the factories of many of the Italian shotgun makers. They do not test regulate their barrels. The only exception maybe Perazzi. They did show me their pattering board auto system and how it worked, but that does not mean they use it for every gun.
Bernardelli used a grid on the wall and had the barrels in vise, lined up the rings in the barrel to the grid and made adjustments with the barrel vise. They had me look through it a show me, but could not see it.
As far as mono block or chopper lump. I have items of both. I have not had issues with either. Shoot what you want and don't loose sleep over it.

John,
I am envious you got to visit Bernardelli before they closed.
Long ago a Bernardelli Roma 6 28ga was my first SxS.
Last year I visited a gunmaker in Marcheno; as you say none regulate except the top end like maybe Parazzi or F.Lli Rizzini.
And drove past the closed Bernardelli factory.
I found this video of Bernardelli - shows the Piani Fissi barrel at about 13:30
