In particular, the error here says that for dev-libs/liblouis with
USE=3Dtools, you can only have _one_ of the python versions selected;
I'm not sure how you manage yours, but using (e.g.)
/etc/portage/package.use to select only a single python version for
now:

    dev-libs/libluois: PYTHON_SINGLE_TARGET: -* python3_13

(or 3_14!) might help. That's probably a bit of an ugly hack, though,
and best would be to straighten out the Python versions you care about
for your packages (e.g., finding out why both 3_13 and 3_14 were
requested for that package).
