Because I want to use LE and not other CAs.

That's misguided (I'm assuming you're the server admin).

Whether you use any specific CA, like LE, or not, has no security impact.

It's about what your users trust and you don't control that.

In an ideal world I would say you're right. In practice they don't even know who they trust.
