I would not lie about date of last flight I would put in application date of my last LPC as a date of my last flight.
In that case you didn't lie and you can explain that according to EASA definition of RECENCY is that sim level D is the same as flight on real aircraft show them also defeinition of RECENCY and you are fully coverd and honest.
Than you can discuss with them that you will go under OCC and company sim check and line training and that is it.
