There are technologies that become de facto requirements for work in a field. For software, compilers and version control both qualify.
But... what else? These things are rare. It’s not like there’s a new thing that comes along every few years and we all have to jump on or be left behind, and LLMs are the latest. There’s definitely a new thing that comes along every few years and people say we have to jump on or be left behind, but it almost never bears out. Many of those ended up being useful, but not essential.
I see no indication that LLMs or associated tooling are going to be like compilers and version control where you pretty much can’t find anyone making a living in the field without them. I can see them being like IDEs or debuggers or linters where they can be handy but plenty of people do fine without them.
