Maybe I completely missed it but a good LP filter should remove any aliasing, shouldn't it?

Yes, you missed it. It is in the first page

Both yes and no.
It should prevent aliasing if it filters out all frequencies above half of project sampling rate, but only before the conversion to the sampling rate from whatever multiple rate the synthesizer works internally at.
It won't remove anything if the aliasing is already there.

Sort of like how adding white paint to black won't make white.

Sort of... in that the analogy is a bit flawed. It's more like having white paint mixed with glitter. Pouring out half your white + glitter doesn't make the remaining white any more pure.

Aliasing in synths. How to prevent it?
