We are working on a head mounted display which uses a TI DLP chipset (DLP470TP).
That said most newer video frontend chips made for HMDs specifically take DisplayPort and provide MIPI DSI, not LVTTL. So we need an extra converter IC for each port. Since DLP is made by TI I assumed TI will have an IC for this purpose itself. Does it?

That's not an issue, we have considered various solution and all are promising. This specific one which is $10 uses a head mounted display-intended video frontend which is meant to control left and right eye displays in sync and also do splitting. The even/odd pixels can be done on the PC side via shader or a much cheaper smaller FPGAs (10K).
Even with the current design of yours the FPGA you use was determined to be an overkill by my contractor and "Intel Cyclone 10GX" was determined sufficient enough costing about 3x less ($118.9). It can support DisplayPort HBR3 line rate at 4K at 120Hz which is even more than needed (60Hz) which also means no video frontend chip is needed as it is integrated. I suggest to consider this and update the DLPC6421 datasheet.
