As far as I've checked, in chapter 818 it's only said that Oden knew how to read and write the language, but then Momonosuke states that the poneglyph themselves were created by his very distant ancestors. Nothing about Odan being able to write on the stones.

Did he even try to?

When, exactly? The only time I can recall he wrote something in the lost language was Skypiea, and he did so on gold, not its poneglyph.
