Italian Arbitration Law, as amended in 2006, expressly provides for the parties to enter into an arbitration clause concerning their possible tort disputes. Indeed, Article 808(b) of Italian Code of Civil Procedure, as enacted by 2006 reform, sets forth that "The parties may establish, in a specific agreement, that future disputes relating to one or more specific non-contractual relations be decided by arbitrators (…)."
There are only a few reported cases concerning Article 808(b) of Italian Code of Civil Procedure, and therefore it appears that that tool is rarely used. Nonetheless, it could be very helpful: for instance, in the case of related actions, it could prevent the doctrine of "parallel paths" from applying.
A recent decision of the Italian Supreme Court (Supreme Court, VI Civil Chamber, decision no. 20673 of 13 October 2016, Italian text available here) deals with that matter. As far as I know, it is the first decision issued by the Italian Supreme Court concerning the construction of Article 808(b) of Italian Code of Civil Procedure.
