The use of the phrase "curious toddler" is called a metaphor[0], which is a figure of speech[1] used to make writing more interesting.
I apologize for the confusion that caused you to interpret this as a literal, physical, toddler. To restate the point with more straightforward language: it is very easy to disrupt the operation of large language models, because they require computer hardware in stable environments with a large amount of electrical power, and function within an operating system. I have not seen any evidence LLMs are immune to things such as: `kill -9`, `sudo reboot now`, physically unplugging the machine(s) on which they are running, or in the case of the AWS data center, collateral damage during a real-world conflict.
