Yessss

I think I like an alternative that uses full words instead of a string of no sense symbols and mixed case letters.

Something like what What 3 Words does but for short URLs. That would be easy to convey and type

It’s true. If you recognize the URL enough to avoid it, then you’ve been rickrolled without even clicking it. Wirelessly brain rickrolled

Infuriatingly, URL shortners are often used in QR codes because they have a character limit-ish (longer strings make for more detailed QR codes, which are harder to scan from further away so it’s a trade-off). but if the QR points to a shortened link then it’s more difficult to assess where a QR code is pointing without blindly following the link.
