My main use for LLMs is to ask it to give me some boilerplate configuration for some library/tool I am not very familiar with and then look up the docs for the options it spits out. Like:

"give me the terraform configuration for an AWS ECS cluster with 2 services that can talk to each other, with one of them available publicly and the other one private"

Occasionally to give some small self-contained algorithms, for example:

Give me a way to format the difference between dates as human-readable text. For example: 1 day, 16 hours.
