Newbie Q re: setting up w/Amazon

If I am publishing under my LLC, do I set up an Amazon account for the LLC (with federal EIN) separate from my personal account that I’ve had since probably 1998? I’m seeing warnings about “one account per person” (watching a recent Reedsy How to video), but Gemini says to set up a separate account for an LLC w/EIN. (Gemini recently cost me $350 in fees due to bad instructions so I’m running at a low trust level of AI guidence for anything important…)

What’s the cumulative human knowledge out there? Separate Amazon account if using an LLC/FEIN? or use the Personal account with personal Tax info (SSN)? and just note the name of the publisher? (which in my case is a DBA under the LLC…just to complicate it.)

*made a few edits for clarity.

2nd edit: I think Grok has reconciled the conflicting information for me saying that I use my personal Amazon account to sign in to KDP, but when asked the Tax questions I can designate my LLC FEIN and banking info for the publishing/KDP process. Please let me know if any of your understand this differently.
