I do not consider Thermodynamics addresses the conservation of angular momentum.

In quantum mechanics per Planck spin is a quantized parameter which exists in
integral multiples of h/2pie (Planck’s constant divided by 2 pie) in coherent
systems.
In primary particles it does not change as long as they remain primary
particles. For example electrons and positrons always have the same absolute
spin and angular momentum, although one is minus and one is plus , However.
When they get close together they change into two photons each with one quanta
of spin and angular momentum (a net 0 angular momentum given their respective
polarizations established by the direction of their spin vector.)
As far as I know, spin was not a concept established at the time TD was
formulated as a scientific theory. I do not consider it was left out on
purpose. However, TD uses an energy term, enthalpy, which includes particle
kinetic energy as in gases and liquids and phonic energy associated in QM’s
with molecular and nuclear “orbital” spin and angular momentum, which IMHO both
contribute to the heat (enthalpy) of a closed system.
(Nuclear orbital spin is a debated concept and may not entail “orbits” of
sub-nuclear particles,) The nuclear models that integrate the energy
associated with spin are fuzzy at best IMHO.
The models that take nuclear potential and kinetic energy (total energy) and
transform it into phonic spin energy in crystals and other condensed matter as
enthalpy are just as fuzzy. That’s why LENR is not accepted by many
physicists, since there is no theory they understand and does not contradict
the existing “standard theory”.

Angular momentum is a vector quantity and in QM has kinetic energy associated
with it.
Is angular momentum in particles conservative? Does it violate laws of
thermodynamics? Is spin left out of conservative formulas because it
unbalances the results?
