Based on the code above, there is no list: youʼre unconditionally
setting local-abbrev-table to a single table. You'd want something
like:

(define-minor-mode american-minor-mode 
    nil nil nil nil
    (setq local-abbrev-table
          (if american-minor-mode
              (list american-minor-mode-abbrev-table local-abbrev-table))))

which would then fail when adding abbrevs, of course.
