There are lots of open source mentorship programs, some of them accept the kind of folks you are talking about:

I found the best way to contribute to open source is to dive in. Contributing to the open source things you use by fixing issues affecting you is a common way to get involved. If the software you use doesn't have any downsides that affect you, usually they will have an issue tracker, sometimes with "newcomer" tags. In the worse case you can always find some spelling errors using codespell or similar, get those fixed and proceed from there to other static analysis tools and then to reviewing the code and fixing any issues you find.
