There is no way to revert any of the "do not ask again" saved options for any dialog, except to search and modify manually the rc files.
Sometimes, you do not want to be asked again, but only in this session, and sometimes you click on the wrong button...
The state of that checkbox is saved as per-application data, so system settings has no way to know where it is stored.
There should be some widget in kdelibs that simplifies adding such a page to an application's config dialog, similar to the shortcuts editor widget.
Rewording and reassigning to kdelibs.

There is already implemented in KMessageBox::enableAllMessages() the way to enable all the messages again.
I've not seen a widget, but all the applications could use a menu entry to use this method (created automatically by KApplication?) (like VirtualBox does with the warnings).
Yes, that would be a solution for applications that don't offer many such check boxes. Check Konversation, it has a page to re-enable them individually in its config dialog, which makes sense when there are many.
If you would kindly allow me to vent briefly...
I *regularly* (and, indeed, just now) accidentally click on that damnable "do not ask again" checkbox line while trying to hit one of the buttons underneath. Before it registers in my brain that this is going to be a problem, I've already moved the mouse slightly to the correct location and clicked again. Almost every time (after yet another disappointing realization as to what I just did) I then have to go hunting for a way to undo it.
Really, I would be happy if there was a way to remove or lock that checkbox, or make it an "Are you sure?" double-checked type of process. An easier way to unconfigure this in general would be nice, but I'd much prefer to avoid the problem in the first place.
The Dolphin settings: Confirmations - Ask for confirmations in all KDE applications when:
'Executing scripts or desktop files'
It writes/reads ~/.config/kiorc.
In KDE/Plasma 5.27.5 on Debian-12 I still have a problem when opening entries in the
address in Dolphin.
Can be workarounded via:
systemsettings -> Applications -> File Associations -> application/x-desktop
-> Application Preference Order -> Add
