As others have said, tools like linters and formatters would be the first step. Vale is a great one for catching spelling and grammar mistakes in comments and code. If you can't get buy in, then just have the linter/formatter config locally in your repo and not checked in, I've done this when freelancing before. You can also write yourself a checklist to go through before asking for a review, check for common mistakes you've made before that can't be checked by a linter. Sometimes I'll also do a PR review of my own PR before asking for someone else to review it.
