It is given by use power supply rail and its configuration (5V or 3.3V). LPSPI pads can be on both supply levels, either VDD_HV_A or VDD_HV_B (pay attention to excel sheet S32K344_IOMUX.xlsx, embedded in the device’s RM).
VIH/VIL you will find defined in DS, Table 22 and 23.
VOH/VOL I have found it only indirectly stated within IOH and IOL specification as condition for this current measurement.
For instance for IOH_33 condition is VOH >= VDD_HV_A/B - 0.7V
It means V-I characteristic of the pin can be estimated by linear approximation between points and < IOH_33; VDD_HV_A/B - 0.7V> and <0mA ; VDD_HV_A/B>.
The same way IOL_33 condition is VOL <= 0.7V.
It implies V-I characteristic as < IOL_33 ; 0.7V > and < 0mA ; 0V >
However it is expected that SPI output lines and connected to high impedance input, so you can just simplify it to expect VOH = VDD_HV_A/B and VOL = VSS (i.e. 0V).
