That is a bad idea and you shouldn't use a service with that requirement. Use something you can self host, or have the choice of DropBox/iCloud/etc for syncing.
You can self-host bitwarden using the opensource implementation of bitwarden server. It includes everything, even the pro features, and supports multiple accounts for the whole family for example: https://github.com/dani-garcia/vaultwarden
The KeePassXC browser extension doesn't have exactly stellar reviews. As for KeePassXC itself, I'm a little hesitant to use something that makes the UX so painful I have to copy the usernames and passwords.
That said, switching from LastPass to Bitwarden seems a little pointless: yes Bitwarden is a younger company and perhaps hasn't managed to mess up their product yet, but knowing life it's just a matter of time and then I'm at a worse place than where I've started.

Have any led to leakage of users' passwords?
And it appears to be customizable how the Auto-Type types... meaning I don't have to copy-paste anything. Well gee...
Wrt Bitwarden, yes I know I can self-host a server, but, managing servers is a bit of a pain, especially for things which clearly need no server.
1. First off, who's to say LastPass will actually delete my data when I delete my account? Could I in practice be increasing my exposure by starting to use something different?
2. Bitwarden: They look cool but "In September 2022, the company announced $100M series B financing". In my experience, usually, financing = bad.
3. KeePassXC: I'm afraid the UX will be worse. But hey it's in my operating system repos, so perhaps I should just give it a try?
