strange. I use the current Org version from git and Emacs 25.1.

That works for me. The default interpretation of $1 is used and
therefore the value is fed into o-t-s-t-h as string.

That doesn't work. I'm not sure, but I guess it is because you asked for
literal interpretation and it is not clear what that would mean for
09:15:00.
> #+TBLFM: @2$3='(org-time-string-to-hours "$1");N
Here you ask for interpretation as numbers. So the o-t-s-t-h function
sees a stringified 9 as it's parameter value. Near, but still no t-shirt ;).

Well, none of them looks like the one I wrote:
#+TBLFM: @2$3='(* $2 (org-time-string-to-hours "$1"));L
You said, that gives an error, too. I have no idea, why. You can use
(message...) and (type-of ...) to look at the types and values that you
feed into your functions. Maybe that gives some insight?
The variant with converting $2 to a number is:
#+TBLFM: @2$3='(* (string-to-number $2) (org-time-string-to-hours $1))
Since the default interpretation is to use strings, the multiplication
sees $2 as a number and $1 is fed to your function as a string, as
required.
