What’s a suspicious or irregular entry? It’s hard to inspect a log without at least a reference to what a good log might look like. Every device has fairly unique logs, so I doubt there’s an Android log analyzer that can tell you immediately if something is abnormal.
You can always collect a log file yourself that you deem be normal, and you can write some processing code to automatically remove lines that both have in common.
But for what you’re doing, you pretty much have to keep doing what’ve been doing: find big repetitive offenders, remove them, rinse and repeat until it’s all unique lines and hopefully only stuff worth looking at.
