Some context here: These tests pass when ANSI mode is disabled.

More info: subquery_test.py::test_scalar_subquery_struct fails because of a possible bug in libcudf:

E                       Suppressed: com.nvidia.spark.rapids.jni.GpuRetryOOM: injected RetryOOM
E                               at ai.rapids.cudf.ColumnView.hasNonEmptyNulls(Native Method)

...

Somewhere along the way, it appears that the output columns have non-empty null rows. This will need to be fixed in libcudf. I'll raise a separate bug to track this. Edit: https://github.com/NVIDIA/spark-rapids/issues/11090
