There doesn’t appear to be a part for either. I’ll look at the key cap, the led strip can probably be simulated with this one (it lacks a grove connector though) found by a google search of the form “fritzing part rgb led strip” which is the best way to search for parts.
edit:
Here is a part for the key switch. Note pcb view suppressed as not useful.
