There's no technical reason why internal accounting systems didn't post to a Blockchain based ledger.

However most companies don't build their own accounting systems, it's too much of a liability and good luck getting an auditor to sign off on financials from something homegrown.

And I not even sure if a commercial off the shelf blockchain-based accounting system exists, does one?

I agree. Using the main chain obviously costs network fees, which for the high amount of transactions involved in running an exchange is untenable. However, there's no reason an exchange couldn't use its own public blockchain to allow independent auditing.

Not to my knowledge, and I know some crypto projects would love to use a product like this. Could be worth doing some market research.

There is one market where I see a need for this, and it's OSS where transparency is important for building trust.

However, what's holding any company back from releasing a read-only connection to their live financial systems?

There are Ethereum rollups which basically work like that. There is a 7 day window to post a fraud proof.

A cursory search of zk rollups and decentralized exchanges brings up https://blog.kyber.network/zkyber-a-new-dex-trading-experien...

Any experience with them? I'd be curious to see how it holds up in practice.

There's a huge disconnect between the technical execution of blockchain or crypto exchange, and running a business with proper internal controls.

I have no ideas what that means, but the time period for legal discovery is usually around 7 years.
