This drives me nuts and happens all the time as well. To be honest, I unplugged my google home device a while back and haven't missed it. It mostly ended up being a clock for me because I'd try to change the color of my lights to a color that it mustn't have been capable of because I'd have to sit there for minutes listening to it list stores in the area that might sell those colored lights or something. It wouldn't stop. This is just one of many frustrating experiences I'd had with that thing.
