Generative models like latent variable models (e.g. VAE) use directed graphical models and these sort of factorizations as a foundation for learning. In VAEs, Neural nets are used to estimate posteriors/priors to generate samples.
This sort of explicit factorization is helpful in other generative models as well like autoregressive models which are basically ...

As far as I know, it doesn't make sense to say that a probability distribution is i.i.d., as you're saying.
The property i.i.d. is a property of a sequence of random variables.
In your case, the random variables are $z_i = (x_i, y_i)$, so it's not just the input $y_i$ or the label $y_i$, but both.
The rest of the explanation can be taken from the other ...

A sequence of $n$ random variables $z_{1:n} = z_1, z_2, \dots, z_n$ is i.i.d. if
they are identically distributed, i.e. each random variable $z_i$ has the same distribution
the joint distribution of all of them is just the product of the marginal distributions of each r.v.
So, let's imagine a thought experiment in which we throw a coin $n$ times, so you ...
