No, not really. The trope is called “medieval stasis” (in TVT terms anyway) and is fairly common in high fantasy, though. The setting is supposed to be swords and horses, with notes of “technology bad” - which makes sense because what passes for tech in Middle Earth is mostly Saruman fucking around with orcs and that sort of thing.
As for weakening, a lot of that had to do with other things than just technological stagnation.
