It is not a matter for speculation, it has nothing to do with America at all. You have to understand the specific mythological references Tolkien uses. Avallonë (Avalon) and Atalantë (Atlantis) have precedence in real world legend and myth.

Atlantis (Island of Atlas) as referred to by Plato was a separate island continent thought to be located (by later cartographers) in the Atlantic Ocean west of Spain and Africa and east of the Americas. Like Tolkien's Numenor, Atlantis sank beneath the sea in a giant cataclysm.

Avalon (Ynys Afallon/Afallach/Aballac in Welsh), The Isle of the Apple, derived from the Old Irish Emain Ablach), is part of ancient Welsh, Cornish, Breton and Briton myth, and is the land where the wounded King Arthur sailed after his fateful battle with Mordred. It is sometimes related to Glastonbury, and is also cognizant with Tir Na Nog of the Irish, the Fortunate Isle, the Isle of the Young, etc. It is, in essence, what Tolkien would refer to as "Faery", the netherworld.

The Americas were a different land mass altogether and not referred to by Tolkien. Such a land mass most likely did not come about until after Eru reshaped the world during the destruction of Numenor.
