Hi @Jzee , @Alison Mackey,
Thank you for your patience while we checked this with the product team.
The team has confirmed that this issue was identified and addressed in Illustrator 30.3. Files created or re-saved using this version should no longer show these rendering anomalies when placed in InDesign. However, older Illustrator files may still exhibit the issue until they are re-saved using the latest version.
Could you please update to Illustrator 30.3 or later, open the affected AI files, save them again, and then place or relink them in InDesign to see if the issue is resolved?
For reference, this behavior was also being tracked here:

If you're still experiencing the issue in Illustrator 30.3 or any later version, please share a short screen recording showing the complete workflow up to the point where the issue occurs, along with the affected files.
Please package the files using File > Package so that all the required linked assets are included. This will allow us to reproduce the workflow accurately and investigate further.
In the meantime, as a workaround, in Illustrator go to Preferences > File Handling & Clipboard, disable Save in Background, then re-save the affected AI file before placing or relinking it in InDesign.
Looking forward to your update.
Abhishek
