I have a custom field that is being added to my comments form. I need to output it to the wp_list_comments() function. I see how to do that here: https://www.advancedcustomfields.com/resources/get-values-comment/. My question is, is it possible to output this new field within the comments listing without having to re-create the entire comment list structure?
Using ACF, it is not possible to output any of the values stored in it’s field without modifying some template or code associated with the front end of the site. In this case you will need to either build a custom walker class or build a custom callback function for displaying each comment. https://codex.wordpress.org/Function_Reference/wp_list_comments
