Yes, that would be the correct case play. It was intially posted on the NFHS website as an interpretation prior to appearing in the case book for the first time. Since the officials error placed Team B at a disadvantage, the ball is dead immediately and the basket is cancelled. No, it isn't a correctable error but the case book states that the play should be blown dead immediately. We aren't going to further penalize Team B because we didn't blow the whistle quickly enough.

adding anudder error situation.......

After a violation, not subsequent to a made basket, Team B gets the ball on the endline. Team A calls their LAST timeout to setup a full court press. On the ensuing inbound the Lead official incorrectly informs B1 that he can run the endline for the throw-in. B1 runs the endline towards the far sideline (right in front of Team A bench) and executes a throw-in that results in a made basket on the other end by B2. Coach A approaches the scorer's table and requests a time out to address the error in allowing B1 to run the baseline.

Q1. Is this an error that is correctable?

Q2. If not, does Team A get charged a timeout for the stoppage and is it a technical since no TO's left?

Unfortunately, no, yes, and yes. And then yes, you never work that gym again!
