I think it should be

" *\\(" (regexp-opt org-todo-keywords-1 t) "\\)?"

1. Without the 3rd argument regexp-opt generates a non-capturing group. 'word 
generates a capturing group.
2. With the additional space in " \\" I'm no longer able to match any todo in 
my org files.

Yes, I added the space variant to test the "\\)?" -> " \\)?" part of the change.
