pacman -Qi itch
And so on.
If you don’t need them, remove them.
At a very quick search itch seems to be replaced by
https://aur.archlinux.org/packages/itch-setup-bin
but should be also in the chaotic-aur.
For lib32-openssl-1.0
https://security.archlinux.org/package/lib32-openssl-1.0
Removed for security reasons. But there should be a hardened version if needed. To be avoided, in my opinion.
For rootactions-servicemenu
There should be now
https://aur.archlinux.org/packages/rootactions-servicemenu-git
But I’d avoid this stuff as well…
As a general comment, to update your system, AUR packages included, I suggest you should use garuda-update -a
