I could be wrong but I don't think tensorflow 2 supports python 3.9 yet...

It doesn't, at least not from the portage ebuild:

% eix -e tensorflow
* sci-libs/tensorflow
Available versions: (~)2.1.0 (~)2.2.0-r1 (~)2.2.0-r2 (~)2.3.1 {cuda mpi +python xla CPU_FLAGS_X86="avx avx2 fma3 fma4 sse sse2 sse3 sse4_1 sse4_2" PYTHON_TARGETS="python3_6 python3_7 python3_8"}

So the ebuild is consistent with Google's requirements which is sensible.
That doesn't mean tensorflow wouldn't work with 3.9 but that would require
the OP to modify the ebuild if there isn't some testing ebuild out in the
ether somewhere.

I'm sadly stuck running tensorflow on Colab because my monster i7 980
Extreme which has been such a wonderful workhorse for probably 8-10 years
now doesn't have the required instruction sets and I cannot justify
the cost of a new machine for this one program... <sniff>

Thanks.
I have created a local overlay of course.
Tensorflow and all packages which it depends on have python3_9 in
PYTHON_TARGETS.
So, I just want 'emerge' to tell me why it is blocking python3.9. If I
have forgotten to create a local overlay of some of its
dependencies, 'emerge' should say me which dependency is missing
python3_9.

Have you changed PYTHON_COMPAT in your local ebuild?
Have you confirmed that tensorflow works with Python 3.9?
