"But we have exactly the same number of reviewers."
LLMs can help with reviews as well. LLMs are not too bad at reviewing code; GPT 5 for example can find off-by-one, missed returns, all sorts of problems that are localized. I think they have a harder time with issues requiring a higher-level global understanding. I wonder if in the future you could fine-tune an LLM on a big codebase (maybe nightly or something) and it could be the first-level reviewer for all changes to that codebase.
