I wonder if it is possible to get org table formulas to respect numeric

Even to add some functions to Emacs that respect numeric locales, it is
necessary to use e.g. dynamic modules (warning: do not try to change
global locale by setlocale(3), almost certainly something in Emacs will
be broken, a library that allows local locale objects is strongly
preferred).

Emacs documentation says that Emacs uses the value of LC_NUMERIC:
https://www.gnu.org/software/emacs/manual/html_node/emacs/General-Variables.html
It is a confusing statement, see:

The state of numeric locales in Emacs is a little worse than just
unsupported. Mostly "C" is forced for LC_NUMERIC, so e.g. grouping is
not used. However if your locale uses comma "," as decimal separator,
you may be confused by calc results:
M-x calc RET dg RET 123456
123,456
