It’s worth taking the time to setup a style guide for your agent to remove llm-isms like this. Somewhat paradoxically, you can even have the agent help write it. Just include a couple of snippets of “bad” phrasing from previous chats, add some commentary about why it’s bad, and what to replace it with, and put that in your system prompt. I could provide examples but the whole point is that you can tailor it to exactly how you want it. This has the added bonus of being a quick sanity check for model quality. If you start noticing llm-ism appear, then likely the model is not following your instruction’s and the thread should be discarded/you need to switch to a better model
