Since I grew up in a metal-shop, I have only purchased 1 new bike in my life, 1979 Honda XL250L and still have it, out of many I have owned.
The first recommendation I would suggest is going back to the shop that did all the repairs and asking to speak to the main tech that actually did the work and tell the boss you want just a few minutes with them to thank them and give them a gift card or tip, and be prepared to tip them no matter what they say.
Next, I would try to get them alone and just be forthright with them, you love the bike, your just not sure if you should trade it in and get another and ask if it was their bike, would you feel fine with it, I get it's safe, but I like to ride hard and fast, not the norm.
I have un-bent and rebuilt my fair share of frames over the decades, and some were fine and then some, well you get it.
Simply ask if it was your bike is the question...
If the majority of the issues were just parts swapped and the neck and frame stayed true, and no visible joint cracks had to be repaired.
I would say as long as it feels tight and like before the crash, your good, if not move on.
$25K is nothing to the cost of being in a wheelchair.
Good luck....
