As Ian Davies observed, CLDR data is supplemental--not part of the time zone package. That being said...
"Etc/GMT+5" would have been correct for much of Eastern Indiana through 2006 since DST wasn't observed.
(Recall that there's a UNIX-heritage GMT offset sign reversal; use the commands...
...to see that Etc/GMT+5 used to be the right thing.)
Perhaps this particular CLDR data hasn't been updated since 2006.

Subject: Indiana (East) has no DST set in CLDR supplemental data
My team has located and fixed an issue in the CLDR supplemental data for Windows TZ mapping.
Indiana (East) Mapping
1. Change the Etc/GMT+5 type which seems spurious.
2. Change the daylight flag.
<mapZone other="US Eastern Standard Time" type="Etc/GMT+5"/>
<!-- S (GMT-05:00) Indiana (East) -->
<mapZone other="US Eastern Standard Time" type="Indiana (East)"/>
<!-- D (GMT-05:00) Indiana (East) -->
Could you verify?
