Rabbi David Rosen organized a meeting between the Chief Rabbi of Israel (R’ Metzger) and Hindu leaders in 2008 which resulted in a joint declaration which acknowledges that Hinduism is a monotheistic religion, similar to Christianity.
Tosafot and Rema held that Christianity was not avoda zara for goyim.
Meiri’s shita on monotheistic religions is well-known.
I don’t see how one can argue that the God-fearing gentile who prays and raises his kids well and to pray and study scripture can be seen as one of the akum of old.
Meiri, R’ Dovid Zvi Hoffman, and many others hold this way.
