You clearly have no idea about the evil that is Mossad, and what they are capable of. I have no doubt Mossad is involved in this, Thunberg is way to high profile for them not to be involved.
It is very clear from what we know now and you even quoted yourself, that Thunberg is being actively tortured, Mossad is just doing it in ways that don’t sound exactly as torture, but more like some rough handling. But it is in fact torture, and I have no doubt this will be concluded soon by experts too.
