What is the fastest way of getting the last 100k block number + block hash pairs for free? Looking for this data on ethereum mainnet specifically to use in a script

Dune is a front runner for now although technically not free for my use case

How often do you need the data? If infrequent, BigQuery will be fast and free for this dataset.

You can use the Etherscan API with a loop to fetch the last 100,000 block numbers and hashes for free.

you can use cryo https://github.com/paradigmxyz/cryo and the command like cryo blocks --blocks -100000:latest

At that point you might as well sync a node yourself

To me it sounds like the best approach would be to collect every incoming block continuously in order to maintain this data over time. You can then fill your queue backwards sequentially and keep the new blocks coming in. If you try to load too much of the same data all the time, you are probably doing something wrong.

You can either (1) get that by calling eth_ getBlockByNumber https://www.quicknode.com/docs/ethereum/eth_getBlockByNumber or (2) real-time stream Block data into a DB where your script can pull from (https://www.quicknode.com/docs/streams/data-sources#block)
