Many people wants to use AI and this is a private alternative and so feels like appropriate part of the Proton's ecosystem.
"Private" as in only you and Proton can access the messages' unencrypted contents?
This is a far cry from any other of their products where they can't access the user's data.

"Your chats with Lumo are stored with zero-access encryption, so Proton can't see your chat history. Only you can securely access your conversations by logging in to your Proton Account."
Keywords being "stored" and "history".
The LLM doesn't operate with encryption, so it is served and extrudes unencrypted data.
Proton operates the LLM, meaning Proton has access to your unencrypted data.
Comparatively, Proton Drive doesn't leak your files' contents at any point, even to Proton.
The data are not logged, not used to improve the AI, as stated. https://proton.me/support/lumo
Stated can be a long way away from reality. That website statement can be changed at a whim and doesn't have any legal binding.
If you wanna rely on encryption to protect your privacy, you have to be encrypted/protected from the service provider too, that's what E2EE is all about, and what many of Proton's services provide, but Lumo not.
Where are you finding Lumo is not E2EE?
