関数をfunctions.phpでオーバーライドするか、元の関数に基づいて新しい関数を作成することができます。コードを見ると、foreachループに$author_idを含めるだけで十分簡単です。
オリジナルのコードはこちら
これを試して、新しいパラメーター(includeauthorid)を関数呼び出しに追加してください...
$authors = wp_list_authors('html=0&style=none&echo=0&exclude_admin=1&optioncount=0&show_fullname=1&hide_empty=1&orderby=name&order=ASC&includeauthorid=1');
新しい関数-ps元の関数を変更することはお勧めしません。これをfunctions.phpに入れるだけです。
