You can update an iPhone 7 Plus to the latest version of iOS 15 - currently iOS 15.8.3.
I'm not sure why you are seeing a message about being unable to connect to the iTunes Store – but in any event, you cannot update an iPhone 7 Plus to the latest iOS version (iOS 18), or to iOS 17, or to iOS 16. For the iPhone 7 Plus, iOS 15 is the end of the line.
