There are legal requirements in the USA to ensure certain parts of an agreement are “conspicuous” (ie should be made so that consumers/customers don’t miss them). Placing the terms in caps is a historical way to achieve the legal bar for this, so is a legal tradition in the USA. In other legal systems (eg the UK) you don’t get this, it’s a uniquely American phenomenon as far as I know.
