The typing.type_check_only is a documented way to specify that a class or function within a stub file is not present at runtime and should therefore not be referenced outside of an annotation. Currently, pyright (and mypy) do not check for such uses.

This is related to mypy issue python/mypy#9531.

This is included in pyright 1.1.325, which I just published. It will also be included in an upcoming pylance release.
