So I found variable-help for org-odt-category-map-alist.

BTW the variable's help conflicts with the org manual. The manual says, to change the displayed label, you should change the second string for the category, but the help in Emacs indicates it's actually the fourth string.

Manual says:

     (setq org-odt-category-map-alist
           '(("__Figure__" "Illustration" "value" "Figure" org-odt--enumerable-image-p)))

Should be:

     (setq org-odt-category-map-alist
           '(("__Figure__" "Figure" "value" "Illustration" org-odt--enumerable-image-p)))

But it's still not working. Maybe I'm misunderstanding the fields. I thought keying __Figure__ and __Listing__ both to the OD-VARIABLE "Illustration" would make both of them share one numeric sequence:

(setq org-odt-category-map-alist
      '(("__Table__" "Table" "value" "Table" org-odt--enumerable-p)
 ("__Figure__" "Illustration" "value" "Figure" org-odt--enumerable-image-p)
 ("__MathFormula__" "Text" "math-formula" "Equation" org-odt--enumerable-formula-p)
 ("__DvipngImage__" "Equation" "value" "Equation" org-odt--enumerable-latex-image-p)
 ("__Listing__" "Illustration" "value" "Figure" org-odt--enumerable-p)))

... but they still get separate counters.

One suspicious thing in content.xml:

<text:sequence-decls>
<text:sequence-decl text:display-outline-level="2" text:name="Table"/>
<text:sequence-decl text:display-outline-level="2" text:name="Illustration"/>
<text:sequence-decl text:display-outline-level="2" text:name="Text"/>
<text:sequence-decl text:display-outline-level="2" text:name="Equation"/>
<text:sequence-decl text:display-outline-level="2" text:name="Illustration"/>
</text:sequence-decls>

Org generates two Illustration counters...?

OK, so org has an inherent limitation that every distinct type of labeled entity must have a separate counter. Well, bother.

I guess next I'm going to try to hack ox-odt.el... (and, mental note, don't write for a journal ever again that won't accept PDF, 'cause the ODT exporter is really not mature by comparison. And don't tell me to write directly in LibreOffice, I have reasons why that is a terrible idea for me. I'll explain them another time if you like.)
