I’d go to the shop and see if they have any suggestions for a fix. Maybe they can recommend a shop.
While it appears that you technically caused the failure, the LBS probably has a bit of responsibility, unless you were warned. I’m willing to bet the vast majority of new riders would do the same thing, especially in today’s environment where there are pages of warnings.
It might be difficult to parse out the company liability ones from the damage to your frame ones. Of course the “Do not operate in an unsafe manner,” kind of blankets anything they may have missed.
