I do not know how to use special blocks. I will read the manual and see
what can be done with those. I f special blocks cannot give a statisfactory
solution (I do not know), other questions you raise may be relevant in
exploring a better solution.

We should be able to add something to #+RESULTS block. I would think that
the natural way would be to specify threeparttable in #+attr_latex. It
would be ideal to put contents of a footer under a separate headline
(tagged noexport) somewhere in the document with a custom_id property. This
custom_id could be specified along with threeparttable in the above
#+attr_latex. Something like the following:

#+attr_latex: threeparttable [[notes_custom_id_1]]
#+RESUlTS:
|x|y|z|
|1|2|2|

* Table notes                                       :noexport:
:PROPERTIES:
:CUSTOM_ID: notes_custom_id_1
:END:
+ first note here
+ second note here
+ third note here

I would think threeparttable be generated when you have something like the
above specified in #+attr_latex.

I use tabulary inside threeparttable (that is, when I give raw latex code).

The code I used has table environment around it. I am no expert on latex
and I must have put it together using whatever I could find on
threeparttable. I cannot say whether this is mandatory. I am sure other
people on this list would just know this. Otherwise, I can experiment.

I am really stretching my capabilities and knowledge of org. So, please
excuse me, if what I said is nonsensical.
