I found this structure "bully somebody into something/into doing something" Source
Ex: If you’re bullied into doing something illegal
The structure is strange to me, so it means someone forces you to do something right?
That's exactly right. It simply means that they coerce you into doing something or force you to do something that normally you would not do. There is really nothing strange about this type of structure. This is actually a very common pattern in English:
The devil pushed me into killing him.
Moms are being manipulated into buying their kids unhealthy food.
It doesn't necessarily have to be a gerund. It can as easily be a noun or a noun phrase:
Dance with me into oblivion.
