You need to explicitly load babel or polyglossia:

For polyglossia (`org-latex-guess-polyglossia-language'):

#+LaTeX_Header: \usepackage[AUTO]{polyglossia}

For babel (`org-latex-guess-babel-language'):

#+LaTeX_Header: \usepackage[bidi=basic]{babel}
#+LaTeX_Header: \babelprovide[import, main]{AUTO}

There was a discussion in an old thread about the possibility of loading
babel or polyglossia automatically (I think Maxim was in favor of it,
and brought up some possibilities). The problem is that babel's syntax
is somewhat more complex than polyglossia's, and admits many variants.
Also in babel there are languages that are loaded using the new ini file
system with the command \babelprovide. Currently,
org-latex-guess-babel-language supports babelprovide, but you need to
load the command explicitly:

#+LaTeX_Header: \babelprovide[options]{AUTO}

BTW I've noticed that the value of #+language is not case-agnostic. You
should put "he". Should it be case-agnostic? In the previous
implementation, when there were two language lists for babel and
polyglossia, neither was it.
