Those things solved problems. Nobody needed to be convinced an iPhone was a good idea; it was an iPod, a PDA, and a newspaper stuffed into a device the size of a credit card that you carried around with you and worked no matter where you were. That's a GREAT idea. No one needed to be convinced about what made an iPhone (or Android, or even Blackberry) a useful and good thing.
Conversely, AWS made starting web businesses no longer require on premises servers, or really knowing anything about servers. You picked what you needed, and if you needed more at some point, you picked that. You could even dynamically allocate and deallocate servers on an incredibly widely available and robust data-center backend. That's HUGE. Numerous massive companies today may not have ever gotten started if not for AWS and it's now making far more money than Amazon's retail business does, and we know how huge it is because East-1 went down some years back, and a third of the freaking Internet stopped working correctly.
What problem even remotely on this level does an LLM solve?
