Was wondering; this is pretty old, Ubuntu 16.04, x86_64.  I don't have
anything bang up to date but I've got some alternatives I can try.

Here's a minimal case:

zsh -fc 'setopt typeset_to_unset
setopt warn_nested_var
unset one
typeset -n ref
() {
  typeset one=ONE
  for ref in one; do
    : ${ref}

No error message; sticking an "un" at the start makes it appear.

I kept the loop in the function to avoid a (correct) additional warning
message setting the global variable ref in the loop.  I don't know if
setting ref in a for loop should actually elide that message, which
is a completely separate issue.
