Does the orange dot at the top mean it is being monitored or tapped?

The orange dot 🟠 (or sometimes red dot 🔴, depending on the screen background) means an app is using the microphone.

Two of the most common apps to use the microphone are the phone app, and the FaceTime app. This microphone use is inherent in making or receiving a call.

To see which app is using the microphone, use Control Center.

From the article above.

An orange indicator  means the microphone

is being used by an app on your iPhone. This indicator appears as an orange square if the Differentiate Without Color setting is on. To enable Differentiate Without Color, go to Settings > Accessibility > Display & Text Size.
