I also don't have an inner monologue and can relate somewhat. However I find that natural language (usually) allows me to be more expressive than pseudocode in the same period of time.

There's also an intangible benefit of having someone to "bounce off". If I'm using an LLM, I am tweaking the system prompt to slow it down, make it ask questions and bug me before making changes. Even without that, writing out the idea displays quickly potential logic or approach flaws - much fast than writing pseudo in my experience.
