ELI5: When a video is lagging/internet cutting out, why does the audio keep playing for a while after the video has stopped?

Because the audio and video are not entirely connected. You can load audio data from a video file without loading the video, and you can load video data from a video file without loading the audio. It's also not necessarily a 1-for-1 ratio - one MB of audio data in a file might cover 30 seconds of audio, whereas one MB of video data in a file might cover half a second of video.
