Yes, that's what it seems to me also, that often a RAG or similar is branded as an "agent". Though I personally understand an LLM agent as something that takes input x to use in LLM inference and then uses the output from that inference to create a new input for another LLM inference that includes the first output and so on, and repeats this >1 times.
That's an LLM workflow and not an agent if it's on rails created by a predefined workflow and doesn't make tool calls, or does not have any choice in tool calls. The tool calls are what give it agency.
Yeah. An agentic workflow is nothing but implementation of execution of a bunch of tasks and each task takes a little bit of help from the LLM. Honestly I believe this is applicable to companies that have workflows having a lot of manual tasks and automation of these workflows could be easier with the help of LLM agents.
