                if msg == 'кик':
                    vk_session.method("messages.removeChatUser", {"chat_id": id, "member_id": event.object.reply_message['from_id']})

Answer 1

The error is in the way you specified member_id, so it will be correct like this:

"member_id": event.object.message['reply_message']['from_id']
