I tried to do something like this one time and had a problem just finding the logs. All information on the internet points to the fact that certain logs exist, but not how to access them. Are they not public access? Do you have a B2B relationship with the companies like Cloudflare that run logs?

They're required to be public services. https://crt.sh/monitored-logs is the list of logs monitored by crt.sh (a public log monitor operated by Sectigo, a commercial CA) if that helps. Each of the major browsers also publishes which logs they trust and provides information about e.g. distrust of logs. Is the problem that you couldn't figure out how to use a log? It doesn't just have a web site where you can type in searches you need to be able to use their web API as defined in the protocol documentation.
