What happens when you try the iRule? Does the client get a redirect? Can you add logging to the iRule and check /var/log/ltm for the output? 

when HTTP_REQUEST {

   log local0. "[IP::client_addr]:[TCP::client_port]: [HTTP::method] request to [HTTP::host][HTTP::uri]"

    Check if host doesn't start with www and has at least one alpha character
   if { not ([string tolower [HTTP::host]] starts_with "www") and [string match {[a-zA-Z]} [HTTP::host]] }{

       Redirect to the same host via https with www. prepended
      HTTP::redirect "https://www.[HTTP::host][HTTP::uri]"

      log local0. "[IP::client_addr]:[TCP::client_port]: Redirecting to https://www.[HTTP::host][HTTP::uri]"
   }
}
