Hello,
On TIDA schematic:

there is series resistor on + of OpAmp and no resistor on - OpAmp input. Is that ok?
Also, is there a 1500Vrms equivalenf for AMC3330DWE? So a Isolated OpAmp with DC/DC?

Hi,
Thanks for reaching out.
Yes, since INN is directly tied to the ground reference (IN this case PE) it is okay to implement the RC filter in a single ended fashion.
No, there is no 1500Vrms isolated amplifier with DC/DC.
Best regards,
Andreas
