How to rescue an overwritten TRUECRYPT partition

Can a PART or a SEGMENT or a BLOCK of a partition encrypted with TRUECRYPT be decrypted regardless of whether the rest of that partition is deleted, damaged, or overwritten?

According to "META" AI:

TRUECRYPT uses a BLOCK CIPHER that divides the partition into INDEPENDENT ENCRYPTION BLOCKS that CAN BE (easily?) DECRYPTED individually using a (never heard of) DATA RECOVERY TOOL

But... "META" didn't mention the name of that RECOVERY TOOL.

And when I asked, META only mentioned expensive (SPONSORED?) apps mainly for BITLOCKER but not for TRUECRYPT, and the rest of them only provide a SUPER (useless) SOLUTION for TRUECRYPT users that consists in "undeleting" recently deleted files from a NOT damaged and NOT overwritten and almost perfect TRUECRYPT partition

Thanks A.I., for sponsoring expensive useless warez
