It works via a shortcode. You have to use the shortcode. There is no auto-identification of possible glossary terms in post content.

Try updating the plugin and re-saving permalinks.

Try the wpg_term_usage_title filter:

add_filter( 'wpg_term_usage_title', 'wpg_term_usage_title' );
function wpg_term_usage_title( $title ){
  return __( 'Term Usage', 'wp-glossary' );
}

I’m not familiar with ‘xili’. If it doesn’t work our of the box, then I probably don’t support it (at the moment), sorry.

If there is a way to perpetuate language settings through some simple setting, then I could look at adding support.

The plugin does not specify a font. It uses whatever font the theme provides.

I’m using it on my own site, which is up-to-date, and it is still working.

The styles and scripts are conditionally loaded. You could explicitly enqueue them yourself, then the mark up should work.
