Hi Seán,
Thank you for raising your concern.
Based on this
document about implementing responsive search ads, it is not utilizing feed services so it appears that this is the reason why you can't get data from the
feed_item.
With this, try using the reports below corresponding to the services that are used to create ad customizer for the said ad type:
ad_group_criterion_customizer
ad_group_customizer
campaign_customizer
customer_customizer
customizer_attribute
Let me know how it goes after trying the provided suggestion.
Regards,
