First, that's not true. You need people to actually write code. If your organization is composed of seniors who are doing architecture planning, cross-team collaboration, etc - you will accomplish approximately nothing. A productive team needs both high level planning and strategy and low level implementation.

Second, the LLM engineer will be able to grow into other roles too. Maybe all of them.

I don't know what type of orgs you have been a part of however in my experience seniors have always been still coding.
