 (file-name-base (cadr (assoc "subfiles" LaTeX-provided-class-options))))

should do the trick, provided that the name of the master file is the
only possible option in \documentclass[...]{subfiles} (I don't know
the class).

Non-existing hooks are not a problem, they're completely fine.  In
this case, `TeX-language-XX-hook' are expected to be created by the
users, according to their needs.  See the manual:

The variable is an alist, so you can query it with `assoc'.  See above.
