I suggest this instead:

  <ul>
    {{ range . }}
      {{ $langName := or .Language.LanguageName .Language.Lang }}
      {{ $langCode := or .Language.LanguageCode .Language.Lang }}
      <li><a href="{{ .RelPermalink }}" hreflang="{{ $langCode }}">{{ .LinkTitle }} ({{ $langName }})</a></li>
    {{ end }}
  </ul>

The language config may not contain either .LanguageName or .LanguageCode.

I did write it like you did at first, but later I found that based on the context configured in this page of the document, the current way of writing should be enough.
I do think the way you provided is more complete, and I would like to write it that way in my own site code.
If you think that's the only way to accept a PR, I'm willing to adjust.
