Well, it depends.
I don't think there is a strong dichotomy. Many philosophers manage also to make sense of free will and accountability under a regime of strict determinism. They are called compatibilists, I think. Atheist philosopher D. Dennet is one of them.
I personally think that true free will is absurd. However, it is like playing roulette. You can effectively apply the laws of probability to something that is inherently deterministic. And that is because the fine details of the balls, the roulette, the air resistence, the initial momentum of both the wheel and the ball, the slight imperfection of the roulette surface, etc. are inscrutable. And tend to cancel each other. So, we settle for a random event, effectively.
In the same way, i think we can settle for freedom of will, even if the underlying processes that lead to a decision acting on the physical Universe, are strictly deterministic. And they cannot be otherwise, if physical information is preserved.

Sounds like plain contradiction.
Heisenberg's uncertainty principle is quite 'scrutable', and provides plenty of wiggle-room
for a free will in the person; and on a Theistic scale; as well as non-corporeal beings too.
When one analyzes such fence-sitting, it results most often in denying free-will except as illusion.
Your mistake is to reduce it to a dichotomy of determinism and 'random'.
Although the word 'random' is defined as complex unpredictable order,
perhaps you would be better of using the word 'chaos'.
But you see, chaos by definition would be incapable of making rational choices
or even approach anything near survival (as a thought process).
Whereas when a philosopher chooses to think about one topic rather than another,
if such a choice were pre-determined, then she would not need to choose to think about that topic,
because being absolutely pre-determined she would know what it is in every logical detail of that topic.
So choosing to think would be impossible.
Pre-determined thought would necessitate absolute knowledge
if every thought was purely logical/causal/determined.
But when we choose to think, it is our only real free choice.
If it were not free, we would already know, and thus not need to choose.
It is our ignorance which liberates us.
And neither could this be a chaotic process or else we would make more awful decisions than we do.
