Let's make some assumptions:
;; list-item.rkt
(define li (class object% ...))
;; add-item.rkt
(define au (class object% ...))
Assuming a third file, main.rkt, links up these two files, why don't you
parameterize the list-item class over add-item:
(define li
(class object% (init-field an-instance-of-add-item)
...
;; And further down you add a method add:
(define/public (callback event . x)
(send an-instance-of-add-item add-item ... stuff ...))
))
