Google will be bringing content and titles related exclusions to the account level in Google Ads AI Max later this year to exclude any unwanted content in their ads at the account level.

Currently, URL exclusions are managed at the campaign level, while URL inclusions are handled at the ad group level. With the upcoming update, AI Max will allow for more refined control, complementing its inventory-aware serving feature, which already excludes out-of-stock items.
Advertisers can expect this feature to roll out within the next six months.
