This jogged my memory of how setopt-local works.  There is only one setter
that was taught to honor it, so far.

Sameer, how about this in your .dir-locals.el file that does
the c-ts-mode-indent-style setter dance?

(
 (c-mode . ((eval . ((progn (setq-local c-ts-mode-indent-style 'bsd)
                            (c-ts-mode-set-style c-ts-mode-indent-style
))))))
 )
