I usually put the cursor on the text that I am interested in, press F11
and switch to char styles or whatever category. The right style would be
highlighted which you can directly inherit from.

The exact scenario you describe here is documented in the manual.

(info "(org) Creating one-off styles")
                                      ^ C-x C-e here 
Look at item 1.

The same node is here:
http://orgmode.org/org.html#Creating-one_002doff-styles

Instead of using an inline markup you can do something like this. 

#+begin_src emacs-lisp
(org-odt-format-fontify "This text is in red" "red-style")
#+end_src

It will mark the text in "red-style". You can similarly use this or this
for marking text in bold.

#+begin_src emacs-lisp
(org-odt-format-fontify "This text is in red" 'bold)
#+end_src

I believe you get the drift now.

Note: There are lot more convenience functions that start with
org-odt-format-* that I use internally to emit OpenDocument tags on the
go.

If you look at OrgOdtStyles.xml (C-h v org-odt-styles-dir) and you can
see a bunch of styles marked as "Org Agenda Styles". These are used for
marking TODO in red and DONE in green etc.

Copy & paste those styles, fix the name and background color and you are
done.
