Think this template produces what you want:
from ttp import ttp
import pprint
data = """
CAM Utilization for ASIC# 0 Max Used
Masks/Values Masks/values

Note: Allocation of TCAM entries per feature uses
a complex algorithm. The above information is meant
to provide an abstract view of the current TCAM utilization

chain="record(asic, asic_name) | void()" - have a look at group functions docs for description, but record stores parent group asic match variable value in cache in variable asic_name, for each next name="CAM" group, that value gets updated
set="asic_name, asic" - retrieves asic_name value from variables cache and assigns it to asic variable within this group result
name="/" - uses absolute path feature to tell that result should be saved at the very top
{{ ignore }}/{{ max }} {{ ignore }}/{{ used }} - ignore statement help to ignore match results
structure="flat_list" - api reference gives good explaination

Hello! I just started to use this library and it looks very handy I am trying to make the output structure as flat as possible, for example I have an input
but the best I could get out of this doesn't quite suit my needs
maybe there is a way to "copy" the variable inside each object or you can advise me something. I would like to get something like this
