There is no scenario in which a 350 million dollar skyscraper deemed "not a safety issue for residents" will be torn down so they can "try again". They'll find a way to stabilize it and that will be that. No one is going to tear down nearly half a billion dollars worth of skyscraper if there's any chance of salvaging it.
It's not without precedent.
In Seattle a cost-cutting method was used to build a 25-story downtown apartment building in 2001.
In 2010 it was found to be flawed and unfixable, and so it was dismantled.
And now there's a new building being built on the site.

Key there is it was deemed unfixable. $350 MM can do a lot of fixing.
Edit: To be clear, I'm not denying the entire possibility. It's just extremely unlikely, especially given that the tower is currently deemed safe.
Plus if it turns out to have been caused by the Trans Bay Terminal, they have very deep pockets (they supposedly spent $58 million on a buttress to protect the Millineum Tower). As does the developer, Millennium Partners and the engineering from firm's insurance companies.
This will get fixed. There will just have to be a big fight to see who has to pay.
In non-earthquake prone areas, it might make sense to jack it up and what not, but not in SF.
