Chomsky offers explicit class analysis:
"Robert Tucker for one has rightly emphasized that Marx sees the
revolutionary more as a frustrated producer, than as a dissatisfied
consumer. And this, far more radical, critique of capitalist
relations of production, flows directly, often in the same words,
from the libertarian thought of The Enlightenment. For this reason,
I think, one must say that classical liberal ideas, in their
essence though not in the way they developed, are profoundly
anti-capitalist. The essence of these ideas must be destroyed for
them to serve as an ideology of modern industrial capitalism."

"A consistent anarchist must oppose private ownership of the means
of production. Such property is indeed, as Proudhon in his famous
remark asserted, a form of theft. But a consistent anarchist will
also oppose the organisation of production by government. I'm
quoting: "it means state socialism, the command of the state
officials over production and the command of managers, scientists,
shop officials, in the shop. The goal of the working class is
liberation from exploitation and this goal is not reached and
cannot be reached by a new directing and governing class
substituting itself for the bourgeoisie. It is only realized by the
workers themselves being the master of production by some form of
workers' councils." These remarks, it happens, are quoted from the
left wing Marxist Anton Pannekoek and in fact radical Marxism, what
Lenin once called infantile ultra leftism, merges with anarchist
currents."

In my view, authoritarianism isn't a particularly important concept in libertarian analysis. More general is "power relations". Power relations is obviously important when analyzing institutions, as it affects outcomes.
Of course, antagonistic interests (as with economic class analysis) is also an important property to look at.
All the best, Tj
