I am not sure about a way to give the KDE System Guard higher
priority, but have you tried Ctrl+Alt+Esc?  This should change your
cursor to an 'X' and you can click on Thunderbird to instantly kill it
(BTW, you can hit Esc again to get your normal cursor back if you
change your mind).  This might bypass the long wait for the System
Guard and you will get to kill the app (which I assume is the point of
opening the System Guard).  The problem might be that Thunderbird is
hogging access to your drive and not letting the System Guard
interrupt.  Whatever the problem is, you should definitely think about
opening a bug report with Mozilla.
