This got me wondering, here I don't have clang in my make.config. The 
main packages using it are:

[I] www-client/firefox
      Installed versions:  123.0.1(rapid)(21:16:32 03/06/24)(X clang ...

[I] mail-client/thunderbird
      Installed versions:  115.8.1(21:14:19 03/07/24)(X clang ...

[I] app-office/libreoffice
      Installed versions:  7.6.5.2^t(21:42:53 03/06/24)(... -clang ...

libreoffice sees it unset because it is not present in the global uses. 
firefox and thunderbird instead set it in the ebuild:

$ grep clang /var/db/repos/gentoo/www-client/firefox/firefox-123.0.ebuild
IUSE="+clang cpu_flags_arm_neon dbus debug eme-free hardened hwaccel"

$ grep clang 
/var/db/repos/gentoo/mail-client/thunderbird/thunderbird-115.8.1.ebuild
IUSE="+clang cpu_flags_arm_neon dbus debug eme-free hardened hwaccel"

Both packages have no issues here with +clang. Given the warning message 
reported by Peter ("Enable USE=clang unless you have a very good reason 
not to.") and the fact that gentoo developers decided to switch it on 
specifically for these packages it would probably be a better idea to 
file a bugzilla rather than forcing the use of GCC, which might fix the 
issue now but lead to problems later. As usual, YMMV.
