Crankshaft Pulley replacement help needed

2zz-ge engine, 2001 body.

I'm going to keep this short and save you all some second hand frustration. I picked up my car this weekend after 4 months of being repaired. New alternator, tensioner belt, PCV bleeder and some solenoid for VVTLI. After driving it for 1, one, hour at speeds between 55 to 75, I heard a loud clunk, looked in my rear view mirror to see if I ran over anything, and see the crankshaft pulley sailing away at ample speed. Took the next exit, looked at the engine, and yep its gone. Somehow the belt was intact too...Got a tow, and now car is at a friend's house.

My questions are:

1. Will this do any permanent damage to the engine?
2. Can I just get a new pulley and put it on there, route the belt and be fine?
3. Is there any way that I can see if the timing is incorrect without dropping the engine and removing the timing chain cover and looking at the teeth? Maybe through the OBD port?

I know a pulley tool can be rented from amazon and have all the manuals...just debating on calling an import/enthusiast shop in town and see what they charge because I live 40 minutes from where the car is located so I can't take other photos.

Open to suggestions/advice and thank you.

I think that it will depend on how and why it came off. For example, is there a broken bolt in the crankshaft? Did the car overheat while the pulley was off? I doubt that the timing would change as long as the chain tensioner was good to begin with.
... The overflow tank cap did not pop out but the bottle was steaming a bit. The engine was run for less than 5 mins total after the pulley flew off. Temps never reached above 220 F from my readings with my code reader...
Well, the steaming is not good. Remember that once the pump stops, the coolant circulation stops also, so you are no longer reading the temperature inside the engine. I would not want to run an engine for 5 minutes without coolant circulation. It is a good thing that your coolant did not blow.
