It would be better to name those files without a prefix dot.  It would
avoid bad surprises.   So assuming that you call those files: config.el
you can easily load these files easily:

   M-x load-file RET ~/some/dir/config.el RET


Actually, if you have a latex file open in that directory, then the
default directory is already that of the latex file where you have
your config.el, so you can just type:

   M-x load-file RET config.el RET


If you only want to change the dictionnary for each latex document,
you could do that with File Variables. (info "(emacs)File Variables")

Put in a comment at the end of the file:

Local Variables:
eval: (ispell-change-dictionary "your-specific-dictionary")
End:

and then when loading again that file, the expression will be
evaluated, and you'll be set.
