It seems to me that the only difference between i2s and left justified is that the word clock is inverted with left justified in respect to i2s. The source, of course, is the nintendo gamecube. The TC9231N circuit has the word clock inverted, but the data and bit clock are just buffered with CMOS SN74HC04.
I2S audio in left-justified mode - Jetson Nano - NVIDIA ...

The ADC is Master and the Jetson board is slave using the audio master clock from the jetson board. The audio format of the ADC is two’s complement, MSB first, left-justified mode, 24 bit PCM, 96 kHz. When the dai-link operates in i2s mode samples are captured as expected. However as the ADC audio is left-justified one bit of each sample is lost.

I2S/Left-Justified/TDM Digital Audio Interface. The AR38U12 is a soft macro IP supporting industry-standard I2S, Left-Justified and Time-Division-Multiplexed (TDM) serial interface to parallel PCM (pulse-code-modulation) data format conversion for digital voice/audio data communication. The IP is highly flexible with enriched programmable features that allow users …

For Left-Justified also known as MSB justified, the Word Select changes when the MSB bit for current frame is available. Serial data is justified to the left, which means that if Word Select’s half period is 32- bit long and only 24 bits are used for audio data, the first 24 bits will be used for audio and the remaining 8 bits must be set to zero.

Right and Left justification can be achieved by adjusting the first to bit of Register 7, which manages the digital audio interface formats. Below is register and its respective content. The changes can be observed on the I2S signal pins. A right justified mode should look like the following. Left Justified mode should look like the following.

Left justified gives you effectively 8 bit conversion as the two least significant bits are in ADRESL. Just read ADRESH. This is often useful when you want a quick and crude result as you can test it directly against a number in W reg or if you are short of space to store results. In this mode, the effective ADC range is: ADRESH = 0 @0V -> 255 @5V.
