I think so.

Junior devs can get plenty of value out of them too, if they have discipline in how they use them - as a learning tool, not as a replacement for thinking about projects.

Senior devs can get SO much more power from these things, because they can lean on many years of experience to help them evaluate if the tool is producing useful results - and to help them prompt it in the most effective way possible.

A junior engineer might not have the conceptual knowledge or vocabulary to say things like "write tests for this using pytest, include a fixture that starts the development server once before running all of the tests against it".
