When the input attenuator is using PIN diodes, only T configuration is used, because PI configuration have difficulties in realizing sufficiently low stray reactances and short transmission line lengths for operation at very high frequencies.
Also when input attenuators are using lumped resistors, T configuration is preferred for flatness up to microwave frequencies.
