When I look int *Org Preview LaTeX Output* buffer, I see a number of
tikz errors when compiling your snippet, including a requirement to use
lualatex.
Latex preview and latex export use a slightly different route to arrive
to final file (tex->dvi->svg vs tex->pdf), so it might be that erroneous
tikz input is processed differently by latex vs pdflatex.
When I fix your snippet to be
\begin{tikzpicture}
\usetikzlibrary {graphs,graphdrawing}
\graph [tree layout, nodes={draw,circle}, sibling sep=0pt, grow=down] {
c -> { a, b -> {c, d}, e }
};
\end{tikzpicture}
I see no issues.
I do not think that it is a bug on Org side. Org correctly messages that
there are problems when exporting to pdf.
