When I enable mypy linting, all errors are attributed to the beginning of the line (column 0) like this:

By default, mypy doesn't emit any column information, but it can be configured to do so using the show_column_numbers option in the configuration file or command line. If column information is emitted, the output parser should be able to take advantage of this additional information.

I was able to fix this by changing the REGEX in mypy.ts to the following:

export const REGEX = '(?<file>[^:]+):(?<line>\\d+)(:(?<column>\\d+))?: (?<type>\\w+): (?<message>.*)\\r?(\\n|$)';

With this change — and with show_column_numbers enabled, the red squiggles now correctly highlight the errant code, making the tool significantly more useful.

The proposed change works both with and without show_column_numbers enabled.

If this fix is acceptable, I'm happy to submit a PR.
