The example I posted earlier in this thread [1] uses the *.tikz version for
latex export.

I do not know, whether that helps, but I think the behaviour of the tikz
graphics has been decided in this thread [2].

The wrapping in tikzpicture if options are present is quite sensible, as
these options have to be presented somewhere.  Note, that it is fine to
nest tikzpicture environments.  So, the *.tikz file is basically
expected to bring its own tikzpicture environment.  If there are options
given in the org file, this is just wrapped into another tikzpicture
environment.  (If I understand the reasoning correctly, that is...)
