You seem to forget the third option: the buddy system (as in, when the bear
shows up, feed him your buddy). This is a very common method of protection
in nature, especially for groups with a very good potential for replacing
lost numbers (i.e., dinosaurs).
>-Small genera would usually use flight, while the larger would choose fight.
Flight & numbers
The whip-tail is a damn good defense, too, as well as sheer bulk.
Size is probably the main defense here.
The big thumb claw might be a good defense.
And as for therizinosauroids: the claws, especially the meter plus long
claws of Therizinosaurus itself, would be a damn good defense, especially in
an animal which sacrificed most of the normal theropod cursorial adaptations.
