While Verizon may not offer a definitive answer, I did stumble across a way to retrieve very old texts. Simply add the PC application to your desktop or laptop. Once it starts up, you'll see it synchronizing for at least 3 or 4 minutes. After it's done, all of the older texts appear in the app, plus your newer ones. I'm sure this is not really intentional by Verizon, but it works for now. So, apparently they do store older texts, but for how long is hard to tell.
If you're a Windows user, just look for it in the Windows Store, it's free.

Keep in mind that the Verizon Cloud app must have already been installed on your phone, and you must have upgraded the service to Premium. Without Premium, only your contacts are backed up. If you have never installed the app, then nothing is backed up.
It would be a good time to at least install the app and decide if you want to upgrade. While Google backs up your contacts also by default (if on Android of course), Google does not backup your photos, messages, etc. Verizons app has the capability to backup Contacts, Photos, Videos, Music, Documents, Messages and Call History. While the free default is contacts, you can upgrade to 500GB of storage for $5/mo, or 1TB for $10/mo. If you think you'll need more than 1TB, then you'll need a different backup option.
