L class have a surface temperature range
of from 2200K to 1400K, and they are named
based upon their spectra. They are about
half way between being stars and brown dwarfs.

Their upper atmosphere is characterised by the
fact that its temperature will allow the condensation
of some types of dust with melting points and boiling
points at extremely high temperatures.

Several questions:

Can anything even remotely with the complexity of
life be automatically excluded in all circumstances
in these temperature ranges?

Is it remotely feasible that the atmospheres of these
low temperature half-star, half-brown-dwarfs could
have other than hydrogen or helium in greater than trace
amounts?

Could non-deuturium fusion remain stable on these stars
for billions of years, maintaining the upper atmosphere
of them at nearly the same temperatures?

What if a life-form on one of these stars tried to
shake your hand? How quickly would it be vaporized?
Could it heal if it happened several years ago?
