iPods have Parental Controls! Pretty much all smartphones/devices do, Samsungs, Androids, Tablets etc. To turn on parental Controls on iPod Touch, go to Settings>General/Privacy depending on your Generation of iPod>Restrictions and enter/make your Restrictions Pass Code. From there, you can edit the ratings that Apps can be downloaded, whether or not apps can be deleted, ban explicit songs etc.

There hasn't been a rise of reported iPod Touches that broke on their own. iPod Touches do have the ability to break, but the construction is pretty sturdy to where it is not often the iPod Touch completely breaks. Although iPod Touches do break, it is not likely they will break on their own.
No, sorry you cannot limit it or block it, but you can delete it and change your itunes password.
