I want to shift my table slightly to the left of the page (exceeding left textwidth boundary). After many googles I however keep having trouble and can't manage to get adjustwidth to work:

It perfectly extends the table to the right, but will not do so for the left side. It does however extend the caption to the left, but not the whole table? Does anybody know why this is? Is it perhaps because of the multitude of used packages?

you have many issues with your table:

• 
  ltablex doesn't work well with adjustwidth. is your table really multi page long?


• use of ltablex preserve X column tape only if cells' contents are wider than standard width of X column, otherwise it shrink column width to width if you have l column tape. a cure is add keepXColumns to document preamble


• regardless that you have contents only one column of table (and others empty), you need to always write all ampersands. adding missed ampersands fixed your mine problem.


• 
  adjustwidth is not intended to change text width of more pages. for this is more appropriate to use newgeometry
  

consider above comments, the table can be written as:

which gives:

if you make Very very very very Long variable name shorter, for example with use of abrevation or with break it into two or more lines, than the use of adjustwidth wouldn't be necessary anymore. in this case use of `ltablex for this table will works as expected:
