In Spring '25, Salesforce introduced an updated user interface (UI) for Advanced Lookup Search.
Reference: Advanced Lookup Search Has an Updated UI
When using the "lightning-input-field" in Lightning Web Component (LWC) to render lookup fields on a record form, the new Advanced Lookup Search UI does not always appear. Whether the new or old UI is displayed depends on whether the logged-in user has the CREATE permission on the object related to the lookup field.

The lightning-input-field in Lightning Web Component does not support creating new records directly from the lookup field dropdown menu. The new Advanced Lookup Search UI (LWC) also does not support inline record creation. As a result, Salesforce falls back to the older Aura-based Advanced Lookup Search UI when the logged-in user has CREATE permission on the related object — because that UI does support creating new records.
For reference, the lightning-input-field Component Reference states:
"Creating a new record from the lookup field's dropdown menu is currently not supported."
The conditional UI behavior is as follows:
