| 1

This will always be 1, regardless of what is in the first element.

As Bruce pointed out, the OP needs to build the list in the first
place as a list of *lists* if the individual elements are to be
treated as lists later.

  set myList [list "{ {" "} }"]
  lindex $myList 0
  => { {
  llength [list [lindex $myList 0]]
  => 1

  set myList [list [list \{ \{] [list \} \}]]
  lindex $myList 0
  => \{ \{
  llength [lindex $myList 0]
  => 2
