Amazons as independents. As for LA, at least these:

Arcoscephale: Sibyls, Priestesses
Midgård: Völva
Utgård: Seithkona, Norna (ugh, can you imagine anything seducing a Gygja? thankfully they aren't available in LA)
Pangaea: Dryads and Black Dryads
Ulm: Fortune Teller

Patala: Nagini are cold-blooded, but I'm not sure if it makes seduction impossible. They are female seducers, though, so it'd be rather ironic.
C'tis: Hierodules are also cold-blooded, but as mere priests shouldn't be worth seducing

I'm not sure if there are others.
