Yes, I agree, there almost certainly is one but I couldn't find it either.
However if you check out auto parts stores they usually have a generic replacement parts section with repair sockets.
I'll bet they will have something that will work.
I did have a thought though.
You could use something like this and just glue it the hole after soldering wires to it, or use a rubber grommet or foam tape to retain it-

Or these because they won't protrude as much-

Because either one of them are compact and are LED they won't get all that hot and you should never have to replace them.
So why even bother with a socket?
That might be another option.
