Is it possible to create a normal bot for code review, maybe there are already a lot of them, and will it be in demand (if created)?

Question

code review

Being an indie developer and first encountering teamwork, I was very surprised by their approach to "code quality".
The style should be the same: they write parentheses with spaces in this file - write it like that.
Each design should be optimal without a single extra part.
You can not repeat, no matter whether it affects performance.
And so on. I still couldn’t get used to all this: you remember old mistakes, but you make new ones. The set of rules is quite large.
And as I understand it, in most teams this is the case.
And of course, reviewers would prefer to get the code right away without all these unnecessary problems.
So I thought - what if there was a bot that would integrate on the github according to the CI principle and check the incoming code?
It is clear that it will be very limited, but maybe it will still be possible to reach a worthwhile level?
Or do they already exist?
The bot could give reviewers a questionnaire on style, or analyze manual reviews for a while and learn.
The bot would make the work of the reviewers doubly easier - firstly, not to write unnecessary comments, and secondly, the bot would simply not let poorly readable code into them, which they have to understand.
