There are even more explicit cases where detailed information about jurors' votes is available. One is Louisiana where the parties are entitled by law to a juror-by-juror poll on each juror's individual verdict.
My understanding is the result of the poll is part of the case transcript and is therefore in principle publicly available (at least these journalists could get their hand on some of it https://www.nola.com/article_25663280-c298-53ef-8182-9a8de046619c.html).

polling and disposition of jury Universal Citation: LA Code Crim Pro
812 (2017)
Art. 812. Same; polling and disposition of jury
The court shall order the clerk to poll the jury if requested by the
state or the defendant. It shall be within the discretion of the court
whether such poll shall be conducted orally or in writing by applying
the procedures of Paragraph (1) or Paragraph (2) of this Article.
(1) Oral polling of the jury shall consist of the clerk's calling each
juror, one at a time, by name. He shall announce to each juror the
verdict returned, and ask him, "Is this your verdict?" Upon receiving
the juror's answer to the question, the clerk shall record the answer.
If, upon polling all of the jurors, the number of jurors required by
law to find a verdict answer "Yes," the court shall order the clerk to
record the verdict and the jury shall be discharged. If, upon polling
all of the jurors, the number required to find a verdict do not answer
"Yes," the jury may be remanded for further deliberation, or the court
may declare a mistrial in accordance with Article 775.
(2) The procedure for the written polling of the jury shall require
that the clerk hand to each juror a separate piece of paper containing
the name of the juror and the words "Is this your verdict?" Each juror
shall write on the slip of paper the words "Yes" or "No" along with
his signature. The clerk shall collect the slips of paper, make them
available for inspection by the court and counsel, and record the
results. If a sufficient number of jurors as required by law to reach
a verdict answer "yes" the clerk shall so inform the court. Upon
verification of the results, the court shall order the clerk to record
the verdict and order the jury discharged. If an insufficient number
required to find a verdict answer "Yes," the court may remand the jury
for further deliberation, or the court may declare a mistrial in
accordance with Article 775.
