Multiple 1099s to same contractor from different LLC owners

[DomsDad]

I acquired an LLC (single-member, California) in April 2019. I have a number of 1099s to generate for people who did work for the LLC for the full year.

Do I generate full-year 1099s for each contractor and "behind the scene" breakdown the payouts for myself and the previous owner's estate for tax returns, or do I do two sets of 1099s for each contractor, one from the previous owner and one from myself, each for the partial year they worked for the respective owners?

The LLC has remained unchanged, other than the name of the owner. The previous owner willed it to me

Yes, you need to complete  the 1099's for the full year as they are being reported by the same legal entity.  This answer would be different if the legal entity and the Tax Identification number had changed.
