Ian-

Your first example is the one I was looking at.

Neither store had anything like a Ground Rod adapter or half inch socket
adapter in stock. I searched the web and was not able to find a ground
rod adapter compatible with SDS+. I found one comment that such an
adapter would not be sufficiently strong to withstand the forces
required to drive a ground rod.

Nah - we're not talking about pile-driving here.

There were several references to an
SDS-Max adapter, but that may not be compatible with SDS+. Yes, the
prices were high!

SDS Max is the next league up in terms of brute performance, weight and
price. For normal ground rods, SDS Max is probably more than you need.

I did find references to a half inch socket adapter. It is a Hitachi
"1/2 inch Chemical Anchor Adapter", Code No. 303044.

No, it's not that one either...

It seems the magic words might be "nut driver":

You use the flat end of the nut driver to hammer on the rod, and to
prevent it from skidding off the end of the rod, you snap on the correct
size of automotive nut-driver socket.

These surely must be available somewhere in the USA, if you can figure
out the right name to ask for.
