Answer 1

In the code you show, mgm_get_google_fonts() is not actually loading fonts, but apparently providing a list of fonts for some other function to load.

The comment in the parent function describes it as providing defaults, so implies that there is some way to override them. From looking through the parent functions.php, you can probably figure out how you can do that.

For example, if the parent theme allows you to override this function, it will probably say something like:

if ( !function_exists( 'mgm_get_google_fonts') {
    ...the function definition you have above...
}

This tests to see if you have defined a function of the same name in your child theme and uses yours if you have.

If the parent theme doesn't do this, they you will need to look where mgm_get_google_fonts is called and track down how to override.
