This is an odd misuse of the term "buzzword." When I think of buzzword, I think of some trendy, cliched phrase, like "Foocorp is a force multiplier that actualizes your vision for maximum impact."
Using an ordinary but less commonly used word with greater than normal frequency does not make it a buzzword. After two years of chatgpt, "delve" is still not that common of a word.
