Feet are one of the things that go *against* them being in Theropoda. Most
theropods have three functional toes and one dewclaw -- Therizinosauroids
have four functional toes.
The hands, with three digits and (in _Alxasaurus_) a semilunate carpal,
are more typically theropodan (specifically coelurosaurian).

Actually, if therizinosauroids are the sister group to oviraptoroids, they
would *be* oviraptorosaurs -- according to The Encyclopedia of Dinosaurs,
Oviraptorosauria is stem-based (all animals sharing more recent ancestry
with _Oviraptor_ than with modern birds).
