How about binding eshell-error-if-no-glob to non-nil when eshell/ls is
called from Dired, then?

That's an unreachable ideal, because there are too many versions of
'ls' out there.  GNU 'ls' is just one of them.  And sometimes the
error comes from the shell which expands wildcards, not from 'ls'
itself.
