I thought you had to buy before boarding on most if not all trains in Italy.
Italy also has ticket validators similar to those in France (or certainly did when I was last there 20 years ago - see my comment on France above) so standard Trenitalia tickets need to be validated before boarding.
On regional trains you can board without a ticket. You must look immediately for the guard and he’ll then sell you a ticket with a small surcharge (5€ IIRC). Failure to do so should get you a fine+ticket price but will most of the times get you the same as above...
