PDF is an odd format, more like an image in many respects than text, so it may be some time before we see LiveCode offer it directly. I know a third party working on an external for that, but it comes encumbered with licensing of another party's library, so it's not cheap. If interest let me know and I'll put you in touch.
But for docx and odt, Curry Kenworthy's WordLib is da bomb. Check it out:
