It's not very useful and `t' is not a valid value there (and
font-lock-mode is enabled by default, so very few people will want to
enable explicitly just for your mode).
BTW, this whole defcustom is unneeded since define-derived-mode already
defines the `rct-mode-hook' for you.

The error says you're calling a function that doesn't exist.

There's `run-hooks' (which you don't need to call since
define-derived-mode does that for you), and there's `add-hook' which
requires one more argument and would be used in the user's .emacs file
rather than in your code.
