I removed that DMARC because you are correct, it was redundant, but now the issue with the FROM address is a problem.
What do you mean be "Removed DMARC"? If you only removed the "DMARC Addresses" setting, but left "DMARC Mitigation = Replace From: with list address" and "DMARC Mitigate unconditionally = Yes", then it's as Thomas mentioned. Most likely your outgoing SMTP gateway is enforcing "From = address of authenticated user" (Google won't even allow you to use a verified alternative from SMTP, you can only use those when using their web client). You probably need to find a different SMTP gateway. (Sorry, can't help; I used my employer's network until I retired, and now I run my own server on a Linode -- which has its own issues, not recommended for the faint of heart or if you need highly reliable outgoing email).
If you removed all your DMARC settings, then I recommend you put them back. Mitigation because that's what puts the list address in there (and that is *all it does*, no other side effects as far as I know). Mitigate unconditionally because that's what you want, the list address in From for all recipients. And Addresses because if you ever change your DMARC settings, it's very likely that not having gmail.com in Addresses will cause lots of bounces for gmail posters. While it has no effect (good or bad) if Mitigate unconditionally = Yes.
When I start a new thread either through e-mail or hyperkitty, it seems to do the same thing.
Since (a) email to Mailman must be sent so that posts will be distributed to the list and (b) normal processing will archive the email as desired, HyperKitty just sends email. It does not try to archive the email directly. So yes, they're going to do the same thing. The only difference is that HyperKitty will use the preferred email of the logged-in user, while (if you know how to do it) you can set the From to whatever you want in email.
