For sure don't in any way respond, just report spam and block the number. Lots of these things are phishing attempts, trying to get you to give personal information (or even money), and aren't connected to the things they mention.
Yep, I looked them up just to see but, like you said, the fact that it exists doesn't mean anything. I didn't find anything (good or bad) associated with that phone number - could be spoofed.
Not true—I just successfully reported this text as junk. It tries to auto-detect spam, and coming from an email address is one of the signs of that, but not the only one.
