>how familiar are LLMs with this technology?

Evil people claim the technology has been promoted entirely for the sake of clearing the ways for LLMs, as it makes more sense from the "perspective" of an ANN than from the perspective of any given human developer.

In a biased Turing test like that, of course the LLM is going to be more proficient than a junior. The junior is slowed down by their vestigial expectation that these very popular tools by very large groups of very smart people actually make sense.
