`org-list-set-checkbox' modifies the structure, i.e., the internal list
representation. It doesn't modify the buffer. You would have to apply
the new structure to the buffer with `org-list-write-struct'.
Anyway, it's much simpler to use `org-toggle-checkbox'.

See `org-list-write-struct' docstring. Basically, STRUCT doesn't match
real structure anymore since step C. You need to provide the original
structure as a third argument so `org-list-write-struct' can modify
buffer by set difference.
(let* ((struct (org-list-struct))
(old (copy-tree struct)))
(org-list-set-checkbox (line-beginning-position) struct "[X]")
(org-list-write-struct struct (org-list-parents-alist struct) old))

But one thing I do not understand. When you do an org-list-write-struct, you want to change the structure. So why is old-struct optional? -- Cecil Westerhof [-- Attachment #2: Type: text/html, Size: 2043 bytes --]

Good question.
IIRC, it's just syntactic sugar since `org-list-write-struct' will do
the `copy-tree' for you in most situations (i.e., when you don't use
a function that modifies structure by side-effect).
