The document loads babel twice:

\usepackage[germanb]{babel} <==
\usepackage[utf8]{inputenc}
\usepackage[LGR,T1]{fontenc}
\usepackage[greek,german]{babel} <==

Hence the 'option class for package babel' error. You have loaded babel
in your org document with the [greek,german] option and (probably, in
the class you are loading) babel is already loaded as well.

Try:

#+LaTeX_Header: \PassOptionsToPackage{greek,german}{babel}
