Will requesting to renew an SSL certificate too many times when it expires be blocked?

@tdba

So I can run the renew command (to renew all the domains I have) once a week

That's a rather low frequency. Certbot by default, if a cronjob or something similar is installed, runs twice a day.

@tdba

without fear of being blocked from requests from certbot or Let's Encrypt, right?

Correct, because:

@tdba

And it seems that certbot will only send requests to Let's Encrypt if that domain is about to expire to avoid Let's Encrypt blocking the request, right?

Partly correct: Certbot will by default request the OCSP status of the certificate when running the renew subcommand. But that doesn't affect the rate limits of the ACME server, so that is not an issue at all. When there's nothing to renew, Certbot won't connect to the ACME API.
