Step 1 is to define "static" variables outside the loop.
Step 2 is to use the full potential of the read command.
Step 3 is to get both termcount and newfilelinecount in one stroke.
Step 4 is to have the sole output at the end of the loop
Code:
searchterm="${1}"
datecurr=$(date +%s)
while IFS="," read file llnum rest
do
  eval $(awk -v llnum=${llnum} -v search="$searchterm" '
NR>llnum && $0~search {++tcnt}
END {print "termcount=" tcnt+0, "newfilelinecount=" NR}
' $file)
  echo "${file},${newfilelinecount},${termcount},${datecurr}"
done < log.txt > /tmp/log.txt_2
