Answer 1

AppInsights is deactivated for the web app.
The possibility of getting the telemetry information after deactivating the Application Insights from the Web App.
Maybe in your Application, you may hardcode the configuration of Application Insights in the Web APP.
Make sure if you use custom telemetry in your application, it must contain the Application Insights configuration.
To Avoid getting the telemetry information from a web app you can try to remove the hardcoded Application Insights configuration
Refer here to remove application insights in multiple ways.
