_Phorusrhacus_. Formerly known as _Phororhacus_ (If I had my way, it still
would be. The latter is etymologically better as well as easier to say.) I
can't seem to figure out what it means. My Greek dictionary gives me weird
translations like "ragged tribute".

No (except in that they are all birds). It appears that these were giant
relatives of the extant South American seriemas.

They are apparently the basalmost living birds, but they branched off after
the hesperornithiforms and ichthyornithiforms (and thus also after
Enantiornithes, confuciusornithids, _Archaeopteryx_, etc.).

Not sure what you're asking. Ratites are no more closely related to non-bird
theropods than other birds are. To put it another way, all living birds
(including ratites) are more closely related to each other than they are to
any non-bird theropod.
