You could filter a Get Events call with the metric ID of the Opened Email metric and the profile ID of the specific profile.

filter
Allowed field(s)/operator(s):
metric_id:equalsprofile_id:equals
You can’t filter on a specific campaign or flow message ID but the event properties will include the campaign or flow ID, and you can also add a time range to the filter.

If you have the CDP add-on, you can also set up webhooks for events like Opened Email: https://help.klaviyo.com/hc/en-us/articles/17760478970907
