 in for a strict CSP should have a newer version of WordPress than 5.7.
 Could the existing theme functions simply check if the
 `wp_print_inline_script_tag` function exists and print/echo if not?

 This is a good point. If the functions aren't available, then a site
 wouldn't be able to opt-in to Strict CSP anyway since the other core code
 wouldn't be using them. So yes, I think directly printing the scripts as
 you suggest would make sense if the functions aren't available.
