Usenet provider. I suggest if you make the jump, then Newshosting is a great option. Why: 5557 days of retention, up to 100 connections, and unlimited download (on highest plan $15/month).
Also Newshosting offers a FREE TRIAL. From there T&C - “Free Trial ends in 14 days or 30GB used, whichever comes first.” You might have to do a CC upfront, but just cancel it the next day, and run the free 2 weeks.
Will you find Italian content. YES, there is tons of it. How do I know? Because I host a Usenet indexer/scraper, and I see everything that is scraped on my server. English, German and Italian are among the top 5 languages.
NZBFind. That is a scraper/indexer. You still need a Usenet provider. The indexers just provide you with the NZB, you need the usenet provider (configured in NZBGet or whatever your download *arrr is) to get all the “parts” (binary posts) and assemble them together.
