I don't know what GUI tools still exist for manipulating GTK2 themes in non-GTK environments—I remember it as being a painful experience that drove me to the command line within an hour.
There is LXAppearance, which has both GTK2 and GTK3 versions. Also, if gtk2-tqt-engine is installed, the GTK theme can be set via TCC.
I have Debian installed, gtk2-tqt-engine is not in their repositories. There is a Trinity package named gtk3-tqt-engine-trinity, but I wouldn't know if that corrects the issue. It's probably on Thunderbird's end.
