That's just not accurate:
1. First off, all the encryption happens client-side. It is possible for anyone so inclined to validate how 1P and LP are doing their encryption.
2. The deficiencies in LP's encryption approach were well known for years.
My point it, yes, companies will spin things how ever they want, which is why you should completely ignore what they say and only evaluate what is verifiable. And 1P's and LP's approaches are verifiably different.
With respect to your confidence in 1Password's code and encryption methodology, would you be willing to send me your 1Password vault so that I can have a look at it?
It's Javascript running in a browser.

Yes, absolutely (note I don't actually know how to get the encrypted version of the vault standalone). Are you willing to send banking information over HTTPS? It's the same level of security.
I believe that, given that it's just JavaScript in the browser, that the encrypted vault should be available as a blob in one of the network requests when you are making a change to the vault.

Maybe I'm being irrational, but I just think there is a fundamental difference in the risk profile between a breach of my banking credentials and having every stored set of credentials across my entire digital life exposed through a password vault breach.
If my banking details were compromised somehow, I at least have a bank I can work with and real people I can talk to. Both the bank and myself have a strong mutual interest in addressing the acute security issue. Government banking regulations come into play. Insurance comes into play.
If my password vault is compromised and credentials for every service and website are exposed, I would argue that is a far graver matter. And who do I turn to in that case? I have to imagine that any of these password management companies would just point to me being somehow negligent with my master key and tell me to pound sound.
With their very comprehensive whitepaper and Charles Proxy you can verify all their claims. Their whitepaper is one of the best resources I have found on E2EE. With that, you should be able to write your own 1P vault parser.
